Artix‐7 FPGAs Data Sheet: DC and AC Switching Characteristics DS181 (v1.26) March 23, 2021 Product Specification Introduction Artix®-7 FPGAs are available in -3, -2, -1, -1LI, and -2L speed grades, with -3 having the highest performance. The Artix-7 FPGAs predominantly operate at a 1.0V core voltage. The -1LI and -2L devices are screened for lower maximum static power and can operate at lower core voltages for lower dynamic power than the -1 and -2 devices, respectively. The -1LI devices operate only at VCCINT = VCCBRAM = 0.95V and have the same speed specifications as the -1 speed grade. The -2L devices can operate at either of two VCCINT voltages, 0.9V and 1.0V and are screened for lower maximum static power. When operated at VCCINT = 1.0V, the speed specification of a -2L device is the same as the -2 speed grade. When operated at VCCINT = 0.9V, the -2L static and dynamic power is reduced. Artix-7 FPGA DC and AC characteristics are specified in commercial, extended, industrial, expanded (-1Q), and military (-1M) temperature ranges. Except the operating temperature range or unless otherwise noted, all the DC and AC electrical parameters are the same for a particular speed grade (that is, the timing characteristics of a -1M speed grade military device are the same as for a -1C speed grade commercial device). However, only selected speed grades and/or devices are available in each temperature range. For example, -1M is only available in the defense-grade Artix-7Q family and -1Q is only available in XA Artix-7 FPGAs. All supply voltage and junction temperature specifications are representative of worst-case conditions. The parameters included are common to popular designs and typical applications.

The recommended power-off sequence is the reverse of the power-on sequence. If VCCINT and VCCBRAM have the same recommended voltage levels then both can be powered by the same supply and ramped simultaneously. If VCCAUX and VCCO have the same recommended voltage levels then both can be powered by the same supply and ramped simultaneously. For VCCO voltages of 3.3V in HR I/O banks and configuration bank 0: • The voltage difference between VCCO and VCCAUX must not exceed 2.625V for longer than TVCCO2VCCAUX for each power-on/off cycle to maintain device reliability levels. • The TVCCO2VCCAUX time can be allocated in any percentage between the power-on and power-off ramps. The recommended power-on sequence to achieve minimum current draw for the GTP transceivers is VCCINT, VMGTAVCC, VMGTAVTT OR VMGTAVCC, VCCINT, VMGTAVTT. Both VMGTAVCC and VCCINT can be ramped simultaneously. The recommended power-off sequence is the reverse of the power-on sequence to achieve minimum current draw. If these recommended sequences are not met, current drawn from VMGTAVTT can be higher than specifications during powerup and power-down. • When VMGTAVTT is powered before VMGTAVCC and VMGTAVTT – VMGTAVCC > 150 mV and VMGTAVCC < 0.7V, the VMGTAVTT current draw can increase by 460 mA per transceiver during VMGTAVCC ramp up. The duration of the current draw can be up to 0.3 x TMGTAVCC (ramp time from GND to 90% of VMGTAVCC). The reverse is true for power-down. • When VMGTAVTT is powered before VCCINT and VMGTAVTT – VCCINT > 150 mV and VCCINT < 0.7V, the VMGTAVTT current draw can increase by 50 mA per transceiver during VCCINT ramp up. The duration of the current draw can be up to 0.3 x TVCCINT (ramp time from GND to 90% of VCCINT). The reverse is true for power-down. There is no recommended sequence for supplies not shown. Table 6 shows the minimum current, in addition to ICCQ, that is required by Artix-7 devices for proper power-on and configuration. If the current minimums shown in Table 5 and Table 6 are met, the device powers on after all four supplies have passed through their power-on reset threshold voltages. The FPGA must not be configured until after VCCINT is applied. Once initialized and configured, use the Xilinx Power Estimator (XPE) tools to estimate current drain on these supplies.

Each designation is defined as follows: Advance Product Specification These specifications are based on simulations only and are typically available soon after device design specifications are frozen. Although speed grades with this designation are considered relatively stable and conservative, some under-reporting might still occur. Preliminary Product Specification These specifications are based on complete ES (engineering sample) silicon characterization. Devices and speed grades with this designation are intended to give a better indication of the expected performance of production silicon. The probability of under-reporting delays is greatly reduced as compared to Advance data. Production Product Specification These specifications are released once enough production silicon of a particular device family member has been characterized to provide full correlation between specifications and devices over numerous production lots. There is no under-reporting of delays, and customers receive formal notification of any subsequent changes. Typically, the slowest speed grades transition to Production before faster speed grades. Testing of AC Switching Characteristics Internal timing parameters are derived from measuring internal test patterns. All AC switching characteristics are representative of worst-case supply voltage and junction temperature conditions. For more specific, more precise, and worst-case guaranteed data, use the values reported by the static timing analyzer and back-annotate to the simulation net list. Unless otherwise noted, values apply to all Artix-7 FPGAs.

To select the 1.0V speed specifications in the Vivado tools, select the Artix-7, XA Artix-7, or Defense Grade Artix-7Q sub-family, and then select the part name that is the device name followed by the package name followed by the speed grade. For example, select the xc7a100tfgg676-3 part name for the XC7A100T device in the FGG676 package and -3 (1.0V) speed grade or select the xc7a100tfgg676-2L part name for the XC7A100T device in the FGG676 package and -2LE (1.0V) speed grade. To select the -1LI (0.95V) speed specifications in the Vivado tools, select the Artix-7 sub-family and then select the part name that is the device name followed by an “i” followed by the package name followed by the speed grade. For example, select the xc7a100tifgg676-1L part name for the XC7A100T device in the FGG676 package and -1LI (0.95V) speed grade. The -1LI (0.95V) speed specifications are not supported in the ISE tools. To select the -2LE (0.9V) speed specifications in the Vivado tools, select the Artix-7 Low Voltage sub-family and then select the part name that is the device name followed by an “l” followed by the package name followed by the speed grade. For example, select the xc7a100tlfgg676-2L part name for the XC7A100T device in the FGG676 package and -2LE (0.9V) speed grade.

The delay varies depending on the capability of the SelectIO input buffer. • TIOOP is described as the delay from the O pin to the IOB pad through the output buffer of an IOB pad. The delay varies depending on the capability of the SelectIO output buffer. • TIOTP is described as the delay from the T pin to the IOB pad through the output buffer of an IOB pad, when 3-state is disabled. The delay varies depending on the SelectIO capability of the output buffer. In HR I/O banks, the IN_TERM termination turn-on time is always faster than TIOTP when the INTERMDISABLE pin is used.

Standard termination was used for all testing. The propagation delay of the trace is characterized separately and subtracted from the final measurement, and is therefore not included in the generalized test setups shown in Figure 1 and Figure 2.

The most accurate prediction of propagation delay in any given application can be obtained through IBIS simulation, using this method: 1. Simulate the output driver of choice into the generalized test setup using values from Table 20. 2. Record the time to VMEAS. 3. Simulate the output driver of choice into the actual PCB trace and load using the appropriate IBIS model or capacitance value to represent the load. 4. Record the time to VMEAS. 5. Compare the results of step 2 and step 4. The increase or decrease in delay yields the actual propagation delay of the PCB trace.

The timing report shows all of these parameters as TRCKO_DO. TRCKO_DOR includes TRCKO_DOW, TRCKO_DOPR, and TRCKO_DOPW as well as the B port equivalent timing parameters. These parameters also apply to synchronous FIFO with DO_REG = 0. TRCKO_DO includes TRCKO_DOP as well as the B port equivalent timing parameters. These parameters also apply to multirate (asynchronous) and synchronous FIFO with DO_REG = 1. TRCKO_FLAGS includes the following parameters: TRCKO_AEMPTY, TRCKO_AFULL, TRCKO_EMPTY, TRCKO_FULL, TRCKO_RDERR, TRCKO_WRERR. TRCKO_POINTERS includes both TRCKO_RDCOUNT and TRCKO_WRCOUNT. The ADDR setup and hold must be met when EN is asserted (even when WE is deasserted). Otherwise, block RAM data corruption is possible. These parameters include both A and B inputs as well as the parity inputs of A and B. TRCO_FLAGS includes the following flags: AEMPTY, AFULL, EMPTY, FULL, RDERR, WRERR, RDCOUNT, and WRCOUNT. RDEN and WREN must be held Low prior to and during reset. The FIFO reset must be asserted for at least five positive clock edges of the slowest clock (WRCLK or RDCLK).

These parameters represent the worst-case duty cycle distortion observable at the I/O flip flops. For all I/O standards, IBIS can be used to calculate any additional duty cycle distortion that might be caused by asymmetrical rise/fall times. The TCKSKEW value represents the worst-case clock-tree skew observable between sequential I/O elements. Significantly less clock-tree skew exists for I/O registers that are close to each other and fed by the same or adjacent clock-tree branches. Use the Xilinx Timing Analyzer tools to evaluate clock skew specific to your application.
