2 Functional Description
2.1
EPP
The ZedBoard features a Xilinx Zynq XC7Z020-1CSG484 EPP. The initial ZedBoards ship with
Engineering Sample "CES" grade silicon. Later shipments will eventually switch to production "C"
grade silicon once they become available. The EPP part markings indicate the silicon grade.
2.2
Memory
Zynq contains a hardened PS memory interface unit. The memory interface unit includes a
dynamic memory controller and static memory interface modules.
2.2.1 DDR3
The ZedBoard includes two Micron MT41K128M16HA-15E:D DDR3 memory components
creating a 32-bit interface. The DDR3 is connected to the hard memory controller in the
Processor Subsystem (PS) as outlined in the Zynq datasheet.
The multi-protocol DDR memory controller is configured for 32-bit wide accesses to a 512 MB
address space. The PS incorporates both the DDR controller and the associated PHY, including
its own set of dedicated I/Os. DDR3 memory interface speeds up to 533MHz (1066Mbs) are
supported.
The DDR3 uses 1.5V SSTL-compatible inputs. DDR3 Termination is utilized on the ZedBoard.
The EPP and DDR3 have been placed close together keeping traces short and matched.
DDR3 on the PS was routed with 40 ohm trace impedance for single-ended signals, and DCI
resistors (VRP/VRN) as well as differential clocks set to 80 ohms. Each DDR3 chip needs its
own 240-ohm pull-down on ZQ.
DDR-VDDQ is set to 1.5V to support the DDR3 devices selected. DDR-VTT is the termination
voltage which is ½ DDR-VDDQ. DDR-VREF is a separate buffered output that is equal to ½
nominal DDR-VDDQ. The DDR-VREF is isolated to provide a cleaner reference for the DDR
level transitions.

For best DDR3 performance, DRAM training is enabled for write leveling, read gate, and read
data eye options in the PS Configuration Tool in Xilinx Platform Studio (XPS). The PS
Configuration tools’ Memory Configuration Wizard contains two entries to allow for DQS to Clock
Delay and Board Delay information to be specified for each of the four byte lanes. These
parameters are specific to every PCB design. Xilinx Answer Record 46778 provides a tool for
calculating these parameters by a printed circuit board design engineers. The Excel worksheet
file ar46778_board_delay_calc.xlsx included in the answer record provides instructions in the
worksheet for calculating these board training details based upon specific trace lengths for certain
DDR3 signals. Using the information from the trace length reports pertaining to the DDR3
interface for ZedBoard these delay values can be recreated by following the directions found in
the Excel worksheet.
The PCB lengths are contained in the ZedBoard PCB trace length reports. The DQS to CLK
Delay and Board Delay values are calculated specific to the ZedBoard memory interface PCB
design. The AR46778 worksheet allows for up to 4 memory devices to be configured for DDR3
4x8 flyby topology. Note that ZedBoard is configured for DDR3 2x16 flyby routing topology. The
first two clock trace midpoint values (CLK0 and CLK1) are used to represent the Micron device
electrically nearest to 7Z020 (IC26) and the second two clock trace midpoint values (CLK2 and
7
1-Aug-2012
CLK3) are used to represent the Micron device electrically furthest from 7Z020 (IC25). The
worksheet calculation results are shown in the following table.

The DQS to CLK Delay fields in the PS7 DDR Configuration window should be populated using
the corresponding values from the previous table.
The configuration fields of the tool may not allow you to input a negative delay value, this is a
known problem with the 14.1 tools and scheduled for correction in the 14.2 tools release. In the
case of DQS2 and DQS3 fields for DQS to CLK Delay, simply enter a value of zero rather than
the negative delay values. This is an acceptable workaround since the calculated values are
relatively close to zero and the values provided in these fields are used as initial values for the
read/write training for DDR3. Keep in mind for LPDDR2 there is no write leveling, and for DDR2
there is no training whatsoever. In these memory use cases, the accuracy of the trace length info
is more important. This is covered in further detail in section 10.6.8 of the Xilinx Zynq TRM,
UG585.

2.2.2 SPI Flash
The ZedBoard features a 4-bit SPI (quad-SPI) serial NOR flash. The Spansion S25FL256S is
used on this board. The Multi-I/O SPI Flash memory is used to provide non-volatile code, and
data storage. It can be used to initialize the PS subsystem as well as configure the PL
subsystem (bitstream). Spansion provides Spansion Flash File System (FFS) for use after
booting the Zynq EPP.
The relevant device attributes are:
256Mbit
x1, x2, and x4 support
Speeds up to 104 MHz, supporting Zynq configuration rates @ 100 MHz
o In Quad-SPI mode, this translates to 400Mbs
Powered from 3.3V
The SPI Flash connects to the EPP supporting up to Quad-I/O SPI interface. This requires
connection to specific pins in MIO Bank 0/500, specifically MIO[1:6,8] as outlined in the Zynq
datasheet. Quad-SPI feedback mode is used, thus qspi_sclk_fb_out/MIO[8] is connected to a
20K pull-up resistor to 3.3V. This allows a QSPI clock frequency greater than FQSPICLK2.
Note: Zynq only supports 24-bit addressing, however the full capacity of the 256Mb Flash can be
accessed via internal bank switching. As of now the S25FL256S is not supported in iMPACT.
Note: 14.x is required for in-direct QSPI Flash Programming.

2.2.3
SD Card Interface
The Zynq PS SD/SDIO peripheral controls communication with the ZedBoard SD Card (A 4GB
Class 4 card is included in the ZedBoard kit.) The SD card can be used for non-volatile external
memory storage as well as booting the Zynq EPP. PS peripheral sd0 is connected through Bank
1/501 MIO[40-47], including, Card Detect and Write Protect.
The SD Card is a 3.3V interface but is connected through MIO Bank 1/501 (1.8V). Therefore, a
TI TXS02612 level shifter performs this translation. The TXS02612 is a 2-port SDIO port
expander with level translation. ZedBoard only makes use of one of these parts. TI offered an
alternative TXS0206 device, but the 0.4mm pitch of that device’s packaging was too fine for our
manufacturer.
Based on the Zynq TRM, host mode is the only mode supported.
The ZedBoard SD Card is connected through a 9-pin standard SD card connector, J12, TE
2041021-1. A Class 4 card or better is recommended.
Note: To use the SD Card, JP6 must be shorted.

USB
2.3.1 USB OTG
ZedBoard implements one of the two available PS USB OTG interfaces. An external PHY with
an 8-bit ULPI interface is required. A TI TUSB1210 Standalone USB Transceiver Chip is used as
the PHY. The PHY features a complete HS-USB Physical Front-End supporting speeds of up to
480Mbs. This part is available in a 32-pin QFN package. VCCio for this device is 1.8V and
cannot be connected through level shifters. The PHY is connected to MIO Bank 1/501, which is
powered at 1.8V. Additionally the USB chip must clock the ULPI interface which requires an
oscillator. A Fox XPRESSO oscillator (767-26-31) is used on ZedBoard.
The external USB interface connects through a TE 1981584-1.
The usb0 peripheral is used on the PS, connected through MIO[28-39] in MIO Bank 1/501.
This USB port will not power the board. However, ZedBoard provides 5V when in Host or OTG
modes. REFCLK pin of TUSB1210 is tied to ground as the EPP will drive the CLOCK input of this
part.

2.3.2 USB-to-UART Bridge
The ZedBoard implements a USB-to-UART bridge connected to a PS UART peripheral. A
Cypress CY7C64225 USB-to-UART Bridge device allows connection to a host computer. The
USB/UART device connects to the USB Micro B connector, J14, (TE 1981584-1) on the board.
Only basic TXD/RXD connection is implemented. If flow control is required this can be added
through Extended MIO on a PL-Pmod™.
Cypress provides royalty-free Virtual COM Port (VCP) drivers which permit the CY7C64225 USBto-UART bridge to appear as a COM port to host computer communications application software
(for example, HyperTerm or TeraTerm). Please refer to the CY7C64225 Setup Guide posted on
zedboard.org for detailed instructions for installing the driver.
The UART 1 Zynq PS peripheral is accessed through MIO[48:49] in MIO Bank 1/501 (1.8V).
Since the CY7C64225 device requires either 3.3V or 5V signaling, a TI TXS0102 level shifter is
used to level shift between 3.3V and 1.8V.

This USB port will not power the board. Therefore, Vbus needs to be connected to 3.3V though a
1KΩ series resistor. The Wake pin, pin 22, connects to GND. A 24Ω series resistor was placed
on each of the data lines, D+ and D-.

2.3.3 USB-JTAG
The ZedBoard provides JTAG functionality based on the Digilent USB High Speed JTAG Module,
SMT1 device. This USB-JTAG circuitry is fully supported and integrated into Xilinx ISE tools,
including iMPACT, ChipScope, and SDK Debugger. Designers who want to re-use this circuit on
their board can do so by acquiring these modules from Avnet.
http://www.em.avnet.com/en-us/design/drc/Pages/Digilent-JTAG-SMT1-Surface-MountProgramming-Module.aspx
The JTAG is available through a Micro B USB connector, J17, TE 1981568-1. TCK has a series
termination resistor, 20-30Ω, to prevent signal integrity issues.
For the JTAG Chain setup, please refer to the Configuration section.

The EPP’s PS subsystem uses a dedicated 33.3333 MHz clock source, IC18, Fox 76733.333333-12, with series termination. The PS infrastructure can generate up to four PLL-based
clocks for the PL system. An on-board 100 MHz oscillator, IC17, Fox 767-100-136, supplies the
PL subsystem clock input on bank 13, pin Y9.
2.6
Reset Sources
2.6.1 Power‐on Reset (PS_POR_B)
The Zynq PS supports external power-on reset signals. The power-on reset is the master reset of
the entire chip. This signal resets every register in the device capable of being reset. ZedBoard
drives this signal from a comparator that holds the system in reset until all power supplies are
valid. Several other IC’s on ZedBoard are reset by this signal as well.

2.6.2 Program Push Button Switch
A PROG push switch, BTN6, toggles EPP PROG_B. This initiates reconfiguring the PLsubsection by the processor.
2.6.3 Processor Subsystem Reset
Power-on reset, labeled PS_RST/BTN7, erases all debug configurations. The external system
reset allows the user to reset all of the functional logic within the device without disturbing the
debug environment. For example, the previous break points set by the user remain valid after
system reset. Due to security concerns, system reset erases all memory content within the PS,
including the OCM. The PL is also reset in system reset. System reset does not re-sample the
boot mode strapping pins.

User I/O
2.7.1 User Push Buttons
The ZedBoard provides 7 user GPIO push buttons to the EPP; five on the PL-side and two on the
PS-side.
Pull-downs provide a known default state, pushing each button connects to Vcco.

10/100/1000 Ethernet PHY
The ZedBoard implements a 10/100/1000 Ethernet port for network connection using a Marvell
88E1518 PHY. This part operates at 1.8V. The PHY connects to MIO Bank 1/501 (1.8V) and
interfaces to the Zynq EPP via RGMII. The RJ-45 connector is a TE Connectivity PlanarMAG
(1840808-7) featuring integrated, auto-wound magnetics that enhance performance, quality and
reliability. The RJ-45 has two status indicator LEDs that indicate traffic and valid link state.
A high-level block diagram of one 10/100/1000 Ethernet interface is shown in the following figure.

Expansion Headers
2.9.1
LPC FMC Connector
A single low-pin count (LPC) FMC slot is provided on the ZedBoard to support a large ecosystem
of plug-in modules. The LPC FMC exposes 68 single-ended I/O, which can be configured as 34
differential pairs. The FMC interface spans over two PL I/O banks, banks 34 and 35. To meet
the FMC spec, these banks are powered from an adjustable voltage set by jumper, J18.
Selectable voltages include 1.8V, default, and 2.5V. It is also possible to set Vadj to 3.3V. Since
3.3V could potentially be the most damaging voltage setting for Vadj, this is not available with the
default board hardware. To set Vadj to 3.3V, solder a short across the 3V3 pads at J18 or solder
in an additional 1x2 header.
WARNING: Before attaching a FMC Card, ensure the correct voltage is selected on jumper, J18.
Failure to do so may result in damage to the FMC card and/or the ZedBoard.
Note, the following LPC FMC connections guidelines were followed:
CLK_#_M2C
– 50 ohm single-ended impedance
– Less than 10mil skew in P/N pair
– Connected to GC (Global Clock) preferential or MRCC (Multi-Region) if not
available
– No length matching to any other feature
LA bus
– 50 ohm single-ended impedance
– Less than 10mil skew in P/N pair
– Less than 100mil length skew across all bits in a bus
• No restriction between LA, HA or HB
– LA Bus 0:16 to be located in one bank
– LA Bus 17:33 to be located in one bank
– CC Pairs 0, 17 to be placed on MRCC pins
– CC Pairs 1, 18 to be placed on SRCC pins
• HB_06_CC optional placed on clock pin if available
To conserve EPP pins, GA[1:0] were removed from EPP and connected to GND.

2.9.2 Digilent Pmod™ Compatible Headers (2x6)
The ZedBoard has five Digilent Pmod™ compatible headers (2x6). These are right-angle, 0.1”
female headers that include eight user I/O plus 3.3V and ground signals as show in the figure
below.
Four Pmod connectors interface to the PL-side of the EPP. These will connect to EPP Bank 13
(3.3V). One Pmod, JE1, connects to the PS-side of the EPP on MIO pins [7,9-15] in EPP MIO
Bank 0/500 (3.3V). Uses for this Pmod include PJTAG access (MIO[10-13]) as well as nine other
hardened MIO peripherals (SPI, GPIO, CAN, I2C, UART, SD, QSPI, Trace, Watchdog).
The four PL Pmod connectors are placed in adjacent pairs on the board edge such that the
clearance between Pin 6 of header #1 and Pin 1 of header #2 is 10mm.
Two of the Pmods, JC1 and JD1, are aligned in a dual configuration and have their I/O routed
differentially to support LVDS running at 525Mbs.
All Pmod data lines, 8 per connector, are protected with two 4-channel TE SESD1004Q4UG0020-090.

2.9.3 Agile Mixed Signaling (AMS) Connector, J2
The XADC header provides analog connectivity for analog reference designs, including AMS
daughter cards like Xilinx’s AMS Evaluation Card.
The analog header is placed close to the LPC FMC header as shown. Both analog and digital IO
can be easily supported for a plug in card. This allows the analog header to be easily connected
to the FMC card using a short ribbon cable as shown. The analog header can also be used
“stand alone” to support the connection of external analog signals.
The pin out has been chosen to provide tightly coupled differential analog pairs on the ribbon
cable and to also provide AGND isolation between channels. The plug in cards which will
facilitate a number of reference designs have not yet been designed so this pin out must provide
a reasonable degree of freedom while also keeping resource requirements as minimal as
possible.
The ZedBoard AMS header is comparable with similar connectors on the Xilinx KC705 and
ZC702 boards. Any AMS plug-in cards built for those boards should be compatible with
ZedBoard as well.

2.10 Configuration Modes
Zynq-7000 EPP devices use a multi-stage boot process that supports both non-secure and
secure boot (note that secure boot is not supported for CES silicon.) The PS is the master of the
boot and configuration process. The following table shows the Zynq configuration modes. Upon
reset, the device mode pins are read to determine the primary boot device to be used: NOR,
NAND, Quad-SPI, SD Card or JTAG.
By default, the ZedBoard uses the SD Card configuration mode. The boot mode pins are
MIO[8:2] and are used as follows:
MIO[2]/Boot_Mode[3] sets the JTAG mode
MIO[5:3]/Boot_Mode[2:0] select the boot mode
MIO[6]/Boot_Mode[4] enables the internal PLL
MIO[8:7]/Vmode[1:0] are used to configure the I/O bank voltages, however these are
fixed on ZedBoard and not configurable
The ZedBoard provides jumpers for MIO[6:2]. These are 1x3 jumpers connected as shown
below. All mode pins can be pulled high or low through a 20 KΩ resistor.
Figure 15 - Configuration Mode Jumpers
These jumpers allow users to change the mode options, including using cascaded JTAG
configuration as well as using the internal PLL.
As noted above, the VMODE pins are strapped permanently to set Bank 500 and 501 voltages to
3.3V and 1.8V. These are not jumper selectable.

The PS boot mode selections are shown in the table below, default setting highlighted in yellow:

Expected configuration time using a 50MB/s QSPI flash is 250ms.
PUDC_B is pulled high on ZedBoard but can be pulled low via JP5. This active-low input enables
internal pull-ups during configuration on all SelectIO pins
A push button labeled “PROG” is connected to the EPP PROG pin, T11, and pulled up. Pushing
the button connects PROG to ground. Upon releasing the button, a re-configuration is initiated.
A blue LED, LD12, should light when the EPP DONE is asserted.
2.10.1 JTAG
As an alternative to using the onboard USB-JTAG interface, the ZedBoard provides traditional
Platform Cable JTAG connector, J15, for use with Xilinx Platform Cables and Digilent JTAG HS1
Programming Cables. The JTAG Chain is constructed as follows:
Figure 16 - ZedBoard JTAG Chain
ZedBoard automatically adds the FMC into the JTAG chain when an FMC card is plugged into
the board via the FMC-PRSNT signal.

2.11 Power
2.11.1 Primary Power Input
The board’s primary input is through a 12V barrel jack. A compatible AC/DC converter will have a
2.5mm inner diameter, 5.5mm outer diameter, center positive connection.
The total power budget is based on 4A from an AC/DC wall wart supply. This rail is protected
with a TE 0603SFF600F/24-2.
A 10mΩ, 1W current sense resistor exists in series with the 12V input power supply. Header J21
straddles this resistor to measure the voltage across this resistor for calculating ZedBoard power.
2.11.2 On/Off Switch
ZedBoard includes an On/Off switch, SW8, to gate 12V. . When SW8 is in the OFF position, 12V
is disconnected from the board.
2.11.3 Regulators

2.11.7 Testing
The power circuitry has been tested to verify compliance with the Zynq power requirements, such
as:
31
1-Aug-2012
Tolerance
o 1.0V Vccint 0.95 to 1.05V
o Vccaux +/- 5%
o Vcco +/-5%
Ramp time
o 0.20 to 50ms
o In-rush current must be controlled so the power circuitry is not overloaded at
start-up
Monotonicity
o No negative dips in Vccint or Vccaux power-up ramps
Sequencing
o Verify sequencing responds as expected based on design
Refer to Zynq Datasheet for the latest requirements
2.11.8 Probes
Two ground test point are available on the board, J3 and J4. This allows easy access to attach
ground leads of two scope probes to the board without having to locate GND pins on a header.

Note: Banks 34 and 35 are powered from an adjustable voltage rail. Jumper, J18, selects this
voltage. Selectable voltages include 1.8V, 2.5V and 3.3V. The 3.3V jumper was intentionally
unpopulated on ZedBoard as these banks primarily connect to the FMC interface and many FMC
cards are only 1.8V and 2.5V compatible. Connecting 3.3V to these cards can damage them, so
leaving this jumper unpopulated reduces the risk of damaging FMC cards.
