Titanium FPGAs contain LEs that are constructed from XLR cells. Each FPGA in the Titanium family has a custom number of building blocks to fit specific application needs. As shown in the following figure, the FPGA includes I/O ports on all four sides, as well as columns of LEs, memory, and DSP blocks. A control block within the FPGA handles configuration. Figure 1: Ti60 FPGA Block Diagram Device Interface Quantum compute fabric DSP Blocks 10K Memory Blocks XLR cell for logic and routing DSP blocks are optimized for computing and AI Interface blocks for GPIO, LVDS, PLL and MIPI lane I/O. www.efinixinc.com 5 Ti60 Data Sheet XLR Cell The eXchangeable Logic and Routing (XLR) cell is the basic building block of the Quantum™ architecture. The Efinix® XLR cell combines logic and routing and supports both functions. This unique innovation greatly enhances the transistor flexibility and utilization rate, thereby reducing transistor counts and silicon area significantly. Learn more: For more detailed on the advantages the XLR cell brings to Titanium FPGAs, read the Why the XLR Cell is a Big Deal White Paper. The XLR cell functions as: • A 4-input LUT that supports any combinational logic function with four inputs. • A simple full adder. • An 8-bit shift register that can be cascaded. • A fracturable LUT or full adder. The logic cell includes an optional flipflop. You can configure multiple logic cells to implement arithmetic functions such as adders, subtractors, and counters.

Memory blocks can operate as single-port RAM, simple dual-port RAM, true dual-port RAM, or ROM. You can initialize the memory content during configuration. The Efinity® software includes a memory cascading feature to connect multiple blocks automatically to form a larger array. This feature enables you to instantiate deeper or wider memory modules. Note: The block RAM content is random and undefined if it is not initialized. The read and write ports support independently configured data widths, an address enable, and an output register reset. The simple dual-port mode also supports a write byte enable. Learn more: Refer to the Quantum Titanium Primitives User Guide for details on the RAM configuration. True Dual-Port Mode The memory read and write ports have the following modes for addressing the memory (depth x width): 1024 x 8 2048 x 4 4096 x 2 8192 x 1 1024 x 10 2048 x 5 Figure 3: RAM Block Diagram (True Dual-Port Mode) Write Data A [9:0] Address A [12:0] Embedded Memory Write Data B [9:0] Address B [12:0] Address Enable B Address Enable A Write Enable B Write Enable A Clock B Clock A Clock Enable B Clock Enable A Reset B Reset A Read Data B [9:0] Read Data A [9:0] Simple Dual-Port Mode The memory read and write ports have the following modes for addressing the memory (depth x width): 512 x 16 1024 x 8 2048 x 4 4096 x 2 8192 x 1 512 x 20 1024 x 10 2048 x 5 Figure 4: Simple Dual-Port Mode RAM Block Diagram (512 x 20 Configuration) Write Data [19:0] Write Address [12:0] Write Enable [1:0] Write Clock Write Clock Enable Write Address Enable Embedded Memory Read Data [19:0] Read Address [12:0] Read Enable Read Address Enable Read Clock Reset RAM output www.efinixinc.com 7 Ti60 Data Sheet DSP Block The Titanium FPGA has high-performance, complex DSP blocks that can perform multiplication, addition, subtraction, accumulation, and 4-bit variable right shifting. The 4-bit variable right shift supports one lane in normal mode, two lanes in dual mode and four lanes in quad mode. Each DSP block has four modes, which support the following multiplication operations: • Normal—One 19 x 18 integer multiplication with 48-bit addition/subtraction. • Dual—One 11 x 10 integer multiplication and one 8 x 8 integer multiplication with two 24-bit additions/subtractions. • Quad—One 7 x 6 integer multiplication and three 4 x 4 integer multiplications with four 12-bit additions/subtractions. • Float—One fused-multiply-add/subtract/accumulate (FMA) BFLOAT16 multiplication. The integer multipliers can represent signed or unsigned values based on the SIGNED parameter. When multiple EFX_DSP12 or EFX_DSP24 primitives are mapped to the same DSP block, they must have the same SIGNED value. The inputs to the multiplier are the A and B data inputs. Optionally, you can use the result of the multiplier in an addition or subtraction operation.

The FPGA has 32 global signals that can be used as either clocks or control signals. The global signals are balanced trees that feed the whole FPGA. The FPGA also has regional signals that can only reach certain FPGA regions, including the top or bottom edges. The FPGA has 4 regional networks for the core, right interface, and left interface blocks. The top and bottom interface blocks have 1 regional clock network each. You can drive the right and left sides of each region independently. Each region also has a local network of clock signals that can only be used in that region. The core's global buffer (GBUF) blocks drive the global and regional signals. Signals from the core and interface can drive the GBUF blocks. Each network has dedicated enable logic to save power by disabling the clock tree. The logic dynamically enables/disables the network and guarantees no glitches at the output. Figure 6: Global and Regional Clock Network Overview 8 Regional Signals 4 Global Signals 4 Interface Only Region 2 2 2 2 Core and Interface Regions 8 8 2 2 2 2 4 4 8 Global Signals Regional Signals Regions for Core and Interface Interface Only Region GBUF RBUF www.efinixinc.com 9 Ti60 Data Sheet Clock Sources that Drive the Global and Regional Networks The Titanium global and regional networks are highly flexible and configurable. Clock sources can come from interface blocks, such as GPIO or PLLs, or from the core fabric. Table 4: Clock Sources that Drive the Global and Regional Networks Source Description GPIO Supports GCLK, GCTRL, RCLK, RCTRL. (Only the P resources support this connection type). LVDS RX Supports GCLK and RCLK. MIPI RX Lane (configured as clock lane) Supports GCLK (default) and RCLK. You can only use resources that are identified as clocks. PLL Output clocks 0 - 3 connect to the global network. Output clock 4 only connects to the regional network in the top or bottom interface regions (depending on the location of the PLL) and can only drive interface blocks on the top or bottom of the FPGA. Refer to Driving the Regional Network on page 16. Oscillator Connects to global buffer. Core Signals from the core logic can drive the global or regional network. www.efinixinc.com 10 Ti60 Data Sheet Driving the Global Network You can access the global clock network using the global clock GPIO pins, PLL outputs, oscillator output, and core-generated clocks. Similarly, the FPGA has GPIO pins that you can configure as control inputs to access the high-fanout network connected to the LE's set, reset, and clock enable signals. A clock multiplexing network controls which interface blocks can drive the global and regional networks. Eight of the clock multiplexers are dynamic (two on each side of the FPGA), allowing you to change which clock drives the global signal in user mode. Learn more: Refer to the Titanium Interfaces User Guide for information on how to configure the global and regional clock networks.

The top and bottom regions are only for the top and bottom interfaces. The other regions are for the core logic (XLR cells, DSP Blocks, and RAM) and the interfaces on the sides. Local Network for Core Logic As shown in the following figure, the regions that contain the core logic are 80 XLR cells tall, and the local network connects an area that is 40 XLR cells tall. Additionally, each column has it's own local network. For example, in the first column, XLR cells 1 - 40 are in the same local network and XLR cells 41 - 80 are in another local network. DSP Blocks and RAM also have their own local networks. This pattern of block/local network is repeated for each column in the die.

These signals can come from several sources: • The global network (32 possible signals) • The core fabric in another region (16 possible signals) • The regional network (4 or 8 possible signals). For the top and bottom regions 8 signals can come from the regional network. For the other regions, 4 signals can come from the regional network. (Refer back to Clock and Control Network on page 9.) Additionally, the local fabric can generate clock and control signals for the local network. The fabric can also drive the clock enable for the XLR cell directly, allowing each XLR cell to have a unique clock enable. Local Network for Interface Regions The following figure shows the local clock networks for the interface blocks. There are a limited number of unique clocks per local clock region. • The top and bottom regions can each support up to 16 unique clock signals; 14 from the global network and 2 from the fabric. • The left and right regions can each support up to 4 unique clock signals. Up to 2 can come from the routing fabric, the rest come from the global or regional buffers.

Because they use the flexible Quantum™ architecture, devices in the Titanium family support a variety of interfaces to meet the needs of different applications. Learn more: The following sections describe the available device interface features in Ti60 FPGAs. Refer to the Titanium Interfaces User Guide for details on the Efinity® Interface Designer settings. Interface Block Connectivity The FPGA core fabric connects to the interface blocks through a signal interface. The interface blocks then connect to the package pins. The core connects to the interface blocks using three types of signals: • Input—Input data or clock to the FPGA core • Output—Output from the FPGA core • Clock output—Clock signal from the core clock tree Figure 15: Interface Block and Core Connectivity FPGA Interface Block Interface Block Signal Interface Input Output Core Input Output Clock Output Clock Output Input Output Input Output Clock Output Clock Output Interface Block Interface Block GPIO GPIO blocks are a special case because they can operate in several modes. For example, in alternate mode the GPIO signal can bypass the signal interface and directly feed another interface block. So a GPIO configured as an alternate input can be used as a PLL reference clock without going through the signal interface to the core. When designing for Titanium FPGAs, you create an RTL design for the core and also configure the interface blocks. From the perspective of the core, outputs from the core are inputs to the interface block and inputs to the core are outputs from the interface block. The Efinity netlist always shows signals from the perspective of the core, so some signals do not appear in the netlist: • GPIO used as reference clocks are not present in the RTL design, they are only visible in the interface block configuration of the Efinity® Interface Designer. www.efinixinc.com 19 Ti60 Data Sheet • The FPGA clock tree is connected to the interface blocks directly. Therefore, clock outputs from the core to the interface are not present in the RTL design, they are only part of the interface configuration (this includes GPIO configured as output clocks). The following sections describe the different types of interface blocks in the Ti60. Signals and block diagrams are shown from the perspective of the interface, not the core. GPIO The Ti60 FPGA supports two types of GPIO: • High-voltage I/O (HVIO)—Simple I/O blocks that can support single-ended I/O standards. • High-speed I/O (HSIO)—Complex I/O blocks that can support single-ended and differential I/O functionality. The I/O logic comprises three register types: • Input—Capture interface signals from the I/O before being transferred to the core logic • Output—Register signals from the core logic before being transferred to the I/O buffers • Output enable—Enable and disable the I/O buffers when I/O used as output The HVIO supports the following I/O standards.

If registered, the input path uses the input clock to control the registers (positively or negatively triggered). Select the alternate input path to drive the alternate function of the GPIO. The alternate path cannot be registered. In DDIO mode, two registers sample the data on the positive and negative edges of the input clock, creating two data streams. Output Only the output path is enabled; optionally registered. If registered, the output path uses the output clock to control the registers (positively or negatively triggered). The output register can be inverted. In DDIO mode, two registers capture the data on the positive and negative edges of the output clock, multiplexing them into one data stream. Bidirectional The input, output, and OE paths are enabled; optionally registered. If registered, the input clock controls the input register, the output clock controls the output and OE registers. All registers can be positively or negatively triggered. Additionally, the input and output paths can be registered independently. The output register can be inverted. Clock output Clock output path is enabled. During configuration, all GPIO pins are configured in weak pull-up mode. During user mode, unused GPIO pins are tristated and configured in weak pull-up mode. You can change the default mode to weak pull-down in the Interface Designer. Double-Data I/O Ti60 FPGAs support double data I/O (DDIO) on input and output registers. In this mode, the DDIO register captures data on both positive and negative clock edges. The core receives 2 bit wide data from the interface. In normal mode, the interface receives or sends data directly to or from the core on the positive and negative clock edges. In resync and pipeline mode, the interface resynchronizes the data to pass both signals on the positive clock edge only. www.efinixinc.com 22 Ti60 Data Sheet Figure 16: DDIO Input Timing Waveform GPIO Input DATA1 DATA2 DATA3 DATA4 DATA5 DATA6 DATA7 DATA8 Clock Normal Mode IN0 DATA1 IN1 DATA3 DATA5 DATA2 DATA4 DATA7 DATA6 DATA8 Resync Mode IN0 DATA1 DATA3 DATA5 DATA2 DATA4 DATA6 DATA8 IN0 DATA1 DATA3 DATA5 DATA7 IN1 DATA2 DATA4 DATA6 DATA8 IN1 DATA7 Pipeline Mode In resync mode, the IN1 data captured on the falling clock edge is delayed one half clock cycle.

In some cases you can use static and dynamic delays at the same time. Table 9: Programmable Delay Support Delay Type Static GPIO Type Description Single-ended 16 steps with approximately 60 ps of delay per step, both input and output paths. Differential RX 64 steps of approximately 25 ps delay per step. You cannot use the static and dynamic delay at the same time. Available only on P input of the HSIO pin pair. Dynamic Differential TX 64 steps with approximately 25 ps of delay per step. Single ended and differential 64 steps with approximately 25 ps of delay per step, input only. Only available on input (RX) delay; available only on P input of the HSIO pin pair. HVIO The HVIOs are grouped into banks. Each bank has its own VCCIO33 that sets the bank voltage for the I/O standard. Each HVIO consists of I/O logic and an I/O buffer. I/O logic connects the core logic to the I/O buffers. I/O buffers are located at the periphery of the device.

There is one programmable VREF per I/O bank. Important: When configuring an I/O pad of the standard's input path as a VREF pin, you must use the VREF from the same physical I/O bank even when the I/O banks are merged to share a common VCCIO pin.

As LVDS, the HSIO has these features: • Programmable VOD, depending on the I/O standard used. • Programmable pre-emphasis. • Up to 1.5 Gbps. • Programmable 100 Ω termination to save power (you can enable or disable it at runtime). • LVDS input enable to dynamically enable/disable the LVDS input. • Support for full rate or half rate serialization. • Up to 10-bit serialization to support protocols such as 8b10b encoding. • Programmable delay chains. • Optional 8-word FIFO for crossing from the parallel (slow) clock to the user’s core clock to help close timing (RX only). • Dynamic phase alignment (DPA) that automatically eliminates skew for clock to data channels and data to data channels by adjusting a delay chain setting so that data is sampled at the center of the bit period. www.efinixinc.com 30 Ti60 Data Sheet Table 14: Full and Half Rate Serialization Mode Description Full rate clock Half rate clock Example In full rate mode, the fast clock runs at the same frequency as the data and captures data on the positive clock edge. Data rate: 800 Mbps In half rate mode, the fast clock runs at half the speed of the data and captures data on both clock edges. Data rate: 800 Mbps Serialization/Deserialization factor: 8 Slow clock frequency: 100 Mhz (800 Mbps / 8) Fast clock frequency: 800 Mhz Serialization / Deserialization factor: 8 Slow clock frequency: 100 Mhz (800 Mbps / 8) Fast clock frequency: 400 Mhz (800 / 2 ) You use a PLL to generate the serial (fast) and parallel (slow) clocks for the LVDS pins. The slow clock runs at the data rate divided by the serialization factor. Ti60 FPGAs do not have a dedicated LVDS clock tree; therefore, the fast and slow clocks must use global or regional clocks to feed the LVDS primitives.

The block supports bidirectional data lane, unidirectional data lane, and unidirectional clock lane which can run at speeds up to 1.5 Gbps. The MIPI lane operates in high-speed (HS) and low-power (LP) modes. In HS mode, the HSIO block transmits or receives data with x8 serializer/deserializer. In LP mode, it transmits or receives data without deserializer/serializer. The MIPI lane block does not include the MIPI D-PHY core logic. A full MIPI D-PHY solution requires: • Multiple MIPI RX or TX lanes (at least a clock lane and a data lane) • Soft MIPI D-PHY IP core programmed into the FPGA fabric The MIPI D-PHY standard is a point-to-point protocol with one endpoint (TX) responsible for initiating and controlling communication. Often, the standard is unidirectional, but when implementing the MIPI DSI protocol, you can use one TX data lane for LP bidirectional communication. The protocol is source synchronous with one clock lane and 1, 2, 4, or 8 data lanes. The number of lanes available depends on which package you are using. A dedicated HSIO block is assigned on the RX interface as a clock lane while the clock lane for TX interface can use any of the HSIO block in the group. www.efinixinc.com 36 Ti60 Data Sheet MIPI RX Lane In RX mode, the HS (fast) clock comes in on the MIPI clock lane and is divided down to generate the slow clock. The fast and slow clocks are then passed to neighboring HSIO blocks to be used for the MIPI data lanes. The data lane fast and slow clocks must be driven by a clock lane in the same MIPI group (dedicated buses drive from the clock lane to the neighboring data lanes). The MIPI RX function is defined as: Table 19: MIPI RX Function MIPI RX Function Description RX_DATA_xy_zz MIPI RX Lane. You can use any data lanes within the same group to form multiple lanes of MIPI RX group. x = P or N y = 0 to 7 data lanes (Up to 8 data lanes) zz = I0 to I11 MIPI RX group (Up to 12 MIPI RX groups) RX_CLK_x_zz MIPI RX Clock Lane. x = P or N zz = I0 to I11 MIPI group Learn more: Refer to the Ti60 Pinout Pinout for more information about the MIPI RX function for each HSIO and for which pins are in the same MIPI group.

The PLLs are located in the corners of the FPGA. You can use the PLL to compensate for clock skew/delay via external or internal feedback to meet timing requirements in advanced applications. The PLL reference clock has up to four sources. You can dynamically select the PLL reference clock with the CLKSEL port. (Hold the PLL in reset when dynamically selecting the reference clock source.)

Assert the RSTN pin for a minimum pulse of 10 ns to reset the PLL. Assert RSTN when dynamically changing the selected PLL reference clock. FBK Input Connect to a clock out interface pin when the PLL is in core feedback mode. IOFBK Input Connect to a clock out interface pin when the PLL is in external I/O feedback mode. CLKOUT0 CLKOUT1 Output PLL output. You can route these signals as input clocks to the core's GCLK network. CLKOUT4 can only feed the top or bottom regional clocks. CLKOUT2 All PLL outputs lock on the negative clock edge. The Interface Designer inverts the clock polarity on the leaf cells by default (Invert Output Clock option unchecked). CLKOUT3 CLKOUT4 You can use CLKOUT0 only for clocks with a maximum frequency of 4x (integer) of the reference clock. If all your system clocks do not fall within this range, you should dedicate one unused clock for CLKOUT0. LOCKED SHIFT[2:0] Output Goes high when PLL achieves lock; goes low when a loss of lock is detected. Connect this signal in your design to monitor the lock status. Input (Optional) Dynamically change the phase shift of the output selected to the value set with this signal. Possible values from 000 (no phase shift) to 111 (3.5 FPLL cycle delay). Each increment adds 0.5 cycle delay. SHIFT_SEL[4:0] Input (Optional) Choose the output(s) affected by the dynamic phase shift. SHIFT_ENA Input (Optional) When high, changes the phase shift of the selected PLL(s) to the new value. www.efinixinc.com 43 Ti60 Data Sheet Table 25: PLL Reference Clock Resource Assignments (W64) PLL REFCLK0 REFCLK1 REFCLK2 External Feedback I/O PLL_TL Single-ended: GPIOL_P_18_PLLIN0 Unbonded(6) Unbonded(6) Single-ended: GPIOL_P_17_EXTFB Differential: GPIOL_P_18_PLLIN0, Differential: GPIOL_P_17_EXTFB, GPIOL_N_18 GPIOL_N_17 PLL_BR Single-ended: GPIOR_P_00_PLLIN0 Unbonded(6) Unbonded(6) Single-ended: GPIOR_P_01_EXTFB Differential: GPIOR_P_00_PLLIN0, Differential: GPIOR_P_01_EXTFB, GPIOR_N_00_CDI22 GPIOR_N_01_CDI23 Table 26: PLL Reference Clock Resource Assignments (F100S3F2) PLL REFCLK0 REFCLK1 REFCLK2 External Feedback I/O PLL_TL Single-ended: GPIOL_P_18_PLLIN0 Unbonded(6) Unbonded(6) Single-ended: GPIOL_P_17_EXTFB Differential: GPIOL_P_18_PLLIN0, Differential: GPIOL_P_17_EXTFB, GPIOL_N_18 GPIOL_N_17 PLL_TR Single-ended: GPIOR_P_19_PLLIN0 Unbonded(6) Unbonded(6) Unbonded(6) Differential: GPIOR_P_19_PLLIN0, GPIOR_N_19 PLL_BR Single-ended: GPIOR_P_00_PLLIN0 Unbonded(6) Unbonded(6) Single-ended: GPIOR_P_01_EXTFB Differential: GPIOR_P_00_PLLIN0, Differential: GPIOR_P_01_EXTFB, GPIOR_N_00_CDI22 GPIOR_N_01_CDI23 Table 27: PLL Reference Clock Resource Assignments (F225) PLL PLL_BL REFCLK0 Single-ended: GPIOB_P_00_PLLIN1 Unbonded(6) Single-ended: GPIOL_P_18_PLLIN0 Single-ended: GPIOT_P_00_PLLIN1 GPIOL_11_PLLIN2 Single-ended: GPIOR_P_19_PLLIN0 Single-ended: GPIOT_P_17_PLLIN1 Unbonded(6) Single-ended: GPIOR_P_00_PLLIN0 Single-ended: GPIOB_P_17_PLLIN1 GPIOR_29_PLLIN2 Differential: GPIOL_P_18_PLLIN0, GPIOL_N_18 PLL_TR Differential: GPIOR_P_19_PLLIN0, GPIOR_N_19 PLL_BR Differential: GPIOR_P_00_PLLIN0, GPIOR_N_00_CDI22 (6) REFCLK2 Single-ended: GPIOL_P_00_PLLIN0 Differential: GPIOL_P_00_PLLIN0, GPIOL_N_00 PLL_TL REFCLK1 Differential: GPIOB_P_00_PLLIN1, GPIOB_N_00 Single-ended: GPIOB_P_01_EXTFB Differential: GPIOB_P_01_EXTFB, GPIOB_N_01 Differential: GPIOT_P_00_PLLIN1 GPIOT_N_00 Single-ended: GPIOL_P_17_EXTFB Differential: GPIOL_P_17_EXTFB, GPIOL_N_17 Differential: GPIOT_P_17_PLLIN1, GPIOT_N_17 Differential: GPIOB_P_17_PLLIN1, GPIOB_N_17 External Feedback I/O Single-ended: GPIOT_P_16_EXTFB Differential: GPIOT_P_16_EXTFB, GPIOT_N_16 Single-ended: GPIOR_P_01_EXTFB Differential: GPIOR_P_01_EXTFB, GPIOR_N_01_CDI23 There is no dedicated pin assigned to this reference clock. www.efinixinc.com 44 Ti60 Data Sheet Dynamic Phase Shift Ti60 FPGAs support a dynamic phase shift where you can adjust the phase shift of each output dynamically in user mode by up to 3.5 FPLL cycles. For example, to phase shift a 400 MHz clock by 90-degree, configure the PLL to have a FPLL frequency of 800 MHz, set the output counter division to 2, and set SHIFT[2:0] to 001. Implementing Dynamic Phase Shift Use these steps to implement the dynamic phase shift: 1. Write the new phase setting into SHIFT[2:0]. 2. After 1 clock cycle of the targeted output clock that you want to shift, assert the SHIFT_SEL[n] and SHIFT_ENA signals. 3. Hold SHIFT_ENA and SHIFT_SEL[n] high for a minimum period of 4 clock cycles of the targeted output clock. 4. De-assert SHIFT_ENA and SHIFT_SEL[n]. Wait for at least 4 clock cycles of the targeted output clock before asserting SHIFT_ENA and SHIFT_SEL[n] again. Note: n in SHIFT_SEL[n] represents the output clock that you intend to add phase shift. The following waveforms describe the signals for a single phase shift and consecutive multiple phase shifts.

The SPI flash memory has a density of 16 Mbits and a clock rate of up to 85 MHz. In active configuration mode, the FPGA is configured using the configuration bitstream in the SPI flash memory. Typically you can fit two compressed bitstream images into the F100S3F2 SPI flash. Important: You cannot enable the Ti60 FPGA security features when using compressed bitstreams. To use active programming mode for the Ti60 F100S3F2 with the SPI flash memory, you must use the SPI Active using JTAG Bridge configuration mode to configure the SPI flash memory.

The SEU detection feature has two modes: • Auto mode—The Ti60 control block periodically runs SEU error checks and flags if it detects an error. You can configure the interval time between SEU checks. • Manual mode—The user design runs the check. In both modes, the user design is responsible for deciding whether to reconfigure the Ti60 when an error is detected. Learn more: For more information on using the SEU detection feature, refer to the Titanium Interfaces User Guide. Internal Reconfiguration Block The Ti60 FPGAs have built-in hardware that supports an internal reconfiguration feature. The Ti60 can reconfigure itself from a bitstream image stored in flash memory. Security Feature The Ti60 FPGA security feature includes: • Intellectual property protection using bitstream encryption with the AES-GCM-256 algorithm • Anti-tampering support using asymmetric bitstream authentication with the RSA-4096 algorithm Important: You cannot enable the Ti60 FPGA security features when using compressed bitstreams. You can enable encryption, authentication, or both. You enable the security features at the project level. www.efinixinc.com 48 Ti60 Data Sheet Figure 38: Security Flow Start Read Bitstream Bitstream Encrypted? no Read Key from Fuse yes RSA Signature AES Decryption RSA-4096 Verification Decryption Key SHA384 Hash Result Comparison Configuration Success yes Match? no Configuration Halts No User Mode End Download: Refer to the Securing Titanium Bitstreams section of the Configuring an FPGA chapter in the Efinity Software User Guide for instructions on how to enable these features. Bitstream Encryption Symmetric bitstream encryption uses a 256-bit key and the AES-GCM-256 algorithm. You create the key and then use it to encrypt the bitstream. You also need to store the key into the FPGA's fuses. During configuration, the Ti60 built-in AES-GCM-256 engine decrypts the encrypted configuration bitstream using the stored key. Without the correct key, the bitstream decryption process cannot recover the original bitstream. www.efinixinc.com 49 Ti60 Data Sheet Bitstream Authentication For bitstream authentication, you use a public/private key pair and the RSA-4096 algorithm. You create a public/private key pair and sign the bitstream with the private key. Then, you save a hashed version of the public key into fuses in the FPGA. During configuration, the FPGA validates the signature on the bitstream using the public key. If the signature is valid, the FPGA knows that the bitstream came from a trusted source and has not been altered by a third party. The FPGA continues configuring normally and goes into user mode. If the signature is invalid, the FPGA stops configuration and does not go into user mode. The private key remains on your computer and is not shared with anyone. The FPGA only has the public key: the bitstream contains the public key data and a signature, while the fuses contain a hashed public key. You can only sign the bitstream with the private key. An attacker cannot re-sign a tampered bitstream without the private key. Disabling JTAG Access Ti60 FPGA's support JTAG blocking, which disables JTAG access to the FPGA by blowing a fuse. Once the fuse is blown, you cannot perform any JTAG operation except for reading the FPGA IDCODE, reading DEVICE_STATUS, and enabling BYPASS mode. To fully secure the FPGA, you must blow the JTAG fuse. Important: Once you blow the fuse, however, you cannot use JTAG ever again in that FPGA (except for IDCODE, DEVICE_STATUS, and BYPASS). So blowing this fuse should be the very last step in your manufacturing process. www.efinixinc.com 50 Ti60 Data Sheet Power Up Sequence You must use the following power up sequence when powering Titanium FPGAs: 1. Power up VCC and VCCA_xx first. 2. When VCC and VCCA_xx are stable, power up all VCCIO and VCCAUX. There is no specific timing delay between the VCCIO pins. Important: Ensure the power ramp rate is within VCCIO/10 V/ms to 10 V/ms. 3. After all power supplies are stable, hold CRESET_N low for a duration of tCRESET_N before asserting CRESET_N from low to high to trigger active SPI programming (the FPGA loads the configuration data from an external flash device). Figure 39: Power Up Sequence VCC VCCA_xx All VCCIO VCCAUX CRESET_N tCRESET_N Max 10 ms Table 30: Connection Requirements for Unused Resources Unused Resource Pin Note HSIO Bank VCCIOxx Connect to either 1.2 V, 1.5 V, or 1.8 V.

Learn more: Refer to AN 030: Using the Titanium Power Estimator for detailed information on FPGA power estimation. Power Supply Current Transient You may observe an inrush current on the dedicated power rail during power-up. You must ensure that the power supplies selected in your board meets the current requirement during power-up and the estimated current during user mode. Use the Power Estimator to calculate the estimated current during user mode.

The user must configure the CRAM for the desired logic function upon power-up and before the FPGA enters normal operation. The FPGA's control block manages the configuration process and uses a bitstream to program the CRAM. The Efinity® software generates the bitstream, which is design dependent. You can configure the Ti60 FPGA(s) in active, passive, or JTAG mode. Figure 40: High-Level Configuration Options Board JTAG Interface SPI Flash Processor Microcontroller FPGA JTAG SPI Data JTAG Mode Controller SPI Active Mode Controller Control Block Configuration Manager User Logic SPI Passive Mode Controller In active mode, the FPGA controls the configuration process. The configuration clock can either be provided by an oscillator circuit within the FPGA or an external clock connected to the EXT_CONFIG_CLK pin. The bitstream is typically stored in an external serial flash device, which provides the bitstream when the FPGA requests it. The control block sends out the instruction and address to read the configuration data. First, it issues a release from power-down instruction to wake up the external SPI flash. Then, it waits for at least 30 μs before issuing a fast read command to read the content of SPI flash from address 24h’000000. In passive mode, the FPGA is the slave and relies on an external master to provide the control, bitstream, and clock for configuration. Typically the master is a microcontroller or another FPGA in active mode. The controller must wait for at least 32 μs after CRESET is deasserted before it can send the bitstream. In JTAG mode, you configure the FPGA via the JTAG interface. www.efinixinc.com 52 Ti60 Data Sheet Supported FPGA Configuration Modes Table 32: Ti60 Configuration Modes by Package Configuration Mode Active Width W64 F100S3F2 F225 X1 X2 X4 X8 Passive – – – X1 X2 X4 JTAG – X8 – – X16 – – (8) X32 – – (8) X1 Learn more: Refer to AN 033: Configuring Titanium FPGAs for more information.

Function Direction Description CLKn Input Single ended input for global clock and control network resource. The number of inputs is package dependent. PLLINn Input PLL reference clock resource. The number of reference clock resources is package dependent. Table 69: Dedicated Configuration Pins These pins cannot be used as general-purpose I/O after configuration. Pins CDONE Direction Description Use External Weak PullUp During Configuration Bidirectional Configuration done status pin. CDONE is an open drain output; connect it to an external pull-up resistor to VCCIO. When CDONE = 1, configuration is complete. If you hold CDONE low, the device will not enter user mode. CRESET_N Input Initiates FPGA re-configuration (active low). Pulse CRESET_N low for a duration of tcreset_N before asserting CRESET_N from low to high to initiate FPGA re-configuration. This pin does not perform a system reset. TCK Input JTAG test clock input (TCK). The rising edge loads signals applied at the TAP input pins (TMS and TDI). The falling edge clocks out signals through the TAP TDO pin. TMS Input JTAG test mode select input (TMS). The I/O sequence on this input controls the test logic operation . The signal value typically changes on the falling edge of TCK. TMS is typically a weak pullup; when it is not driven by an external source, the test logic perceives a logic 1. TDI Input JTAG test data input (TDI). Data applied at this serial input is fed into the instruction register or into a test data register depending on the sequence previously applied at TMS. Typically, the signal applied at TDI changes state following the falling edge of TCK while the registers shift in the value received on the rising edge. Like TMS, TDI is typically a weak pull-up; when it is not driven from an external source, the test logic perceives a logic 1. TDO Output JTAG test data output (TDO). This serial output from the test logic is fed from the instruction register or from a test data register depending on the sequence previously applied at TMS. During shifting, data applied at TDI appears at TDO after a number of cycles of TCK determined by the length of the register included in the serial path. The signal driven through TDO changes state following the falling edge of TCK. When data is not being shifted through the device, TDO is set to an inactive drive state (e.g., high-impedance). (19) CDONE has a drive strength of 12 mA at 1.8 V. www.efinixinc.com 66 Ti60 Data Sheet Table 70: Dual-Purpose Configuration Pins In user mode (after configuration), you can use these dual-purpose pins as general I/O. Pins CBSEL[1:0] Direction Input Description Use External Weak PullUp During Configuration Optional multi-image selection input (if external multi-image configuration mode is enabled). CCK I/O Passive SPI input configuration clock or active SPI output configuration clock. CDIn I/O n is a number from 0 to 31 depending on the SPI configuration. (20) 0: Passive serial data input or active serial output. 1: Passive serial data output or active serial input. n: Parallel I/O. In multi-bit daisy chain connection, the CDIn (31:0) connects to the data bus in parallel. CSI Input Chip select. 0: The FPGA is not selected or enabled and will not be configured. 1: Selects the FPGA for configuration (SPI and JTAG configuration). CSO Output Chip select output. Selects the next device for cascading configuration. (21) N/A NSTATUS Output Status (active low). Indicates a configuration error. When the FPGA drives this pin low, it indicates an ID mismatch, the bitstream CRC check has failed, or remote update has failed. N/A Input Active-low configuration mode select. The FPGA senses the value of SSL_N when it comes out of reset (pulse CRESET_N low to high). SSL_N 0: Passive mode 1: Active mode In active configuration mode, SSL_N serves as a chip select to the flash device 1 (CDI0 - CDI3). SSU_N EXT_CONFIG_CLK TEST_N Input I/O Input In active configuration mode (dual quad mode), SSU_N serves as a chip select to the flash device 2 (CDI4 - CDI7). In active mode, EXT_CONFIG_CLK pin is connected from an external clock, to be used as a configuration clock. Active-low test mode enable signal. Set to 1 to disable test mode. During configuration, rely on the external weak pull-up or drive this pin high. (20) (21) Not applicable to single-image or remote update. Cascaded configuration is not supported in the F100S3F2 package. www.efinixinc.com 67 Ti60 Data Sheet Ti60 Interface Floorplan Note: The numbers in the floorplan figures indicate the HVIO and HSIO number ranges.
