Part 1: AC7Z035B Core Board Introduction
AC7Z035B (core board model, the same below) FPGA core board, ZYNQ
chip is based on XC7Z035-2FFG676 of XILINX company ZYNQ7000 series.
The ZYNQ chip's PS system integrates two ARM CortexTM-A9 processors,
AMBA® interconnects, internal memory, external memory interfaces and
peripherals. The FPGA of the ZYNQ chip contains a wealth of programmable
logic cells, DSP and internal RAM.
The core board uses four Micron 512MB DDR3 chips
MT41J256M16HA-125 for a total capacity of 4GB. Two DDR3s are mounted on
the PS and PL sides, respectively, which form a 32-bit bus width. The DDR3
SDRAM on the PS side can run at up to 533MHz (data rate 1066Mbps), and
the DDR3 SDRAM on the PL side can run at speeds up to 800MHz (data rate
1600Mbps). In addition, two 256MBit QSPI FLASH and 8GB eMMC FLASH
chips are integrated on the core board to boot the storage configuration and
system files.
In order to connect with the carrier board, the four board-to-board
connectors of the core board expand the USB interface, the Gigabit Ethernet
interface, the SD card interface and other remaining IO ports of the PS side;
and also extend the 8-pair high-speed transceiver GTX interface of the ZYNQ,
almost all IO ports (144) on the PL side. The level of IO of BANK12 and
BANK13 can be modified by replacing the LDO chip on the core board to meet
the requirements of different level interfaces of users. For users who need a lot
of IO, this core board will be a good choice. Moreover, the IO connection part,
the routing between the ZYNQ chip and the interface is equal length and
differential processing, and the core board size is only 80*60 (mm), which is
very suitable for secondary development.

Part 2: ZYNQ Chip
The FPGA core board AC7Z035B uses Xilinx's Zynq7000 series chip,
model XC7Z035-2FFG676. The chip's PS system integrates two ARM
CortexTM-A9 processors, AMBA® interconnects, internal memory, external
memory interfaces and peripherals. These peripherals mainly include USB bus
interface, Ethernet interface, SD/SDIO interface, I2C bus interface, CAN bus
interface, UART interface, GPIO etc. The PS can operate independently and
start up at power on or reset. Figure 2-1 detailed the Overall Block Diagram of
the ZYNQ7000 Chip.

Part 3: DDR3 DRAM
The FPGA core board AC7Z035B is equipped with four Micron 512MB
DDR3 chips, model MT41J256M16HA-125 (compatible with
MT41K256M16HA-125), in which Two DDR3s are mounted on the PS and PL
sides respectively. Two DDR3 SDRAMs form a 32-bit bus width. The PS-side
DDR3 SDRAM has a maximum operating speed of 533MHz (data rate
1066Mbps), and two DDR3 memory systems are directly connected to the
memory interface of the BANK 502 of the ZYNQ Processing System (PS). The
PL-side DDR3 SDRAM has a maximum operating speed of 800MHz (data rate
1600Mbps), and two DDR3 memory systems are connected to the BANK33
and BANK34 interfaces of the FPGA. The specific configuration of DDR3
SDRAM is shown in Table 3-1.

The hardware design of DDR3 requires strict consideration of signal
integrity. We have fully considered the matching resistor/terminal resistance,
trace impedance control, and trace length control in circuit design and PCB
design to ensure high-speed and stable operation of DDR3.

FLASH chips to form an 8-bit bandwidth data bus, the flash model is
W25Q256FVEI, which uses the 3.3V CMOS voltage standard. Due to the
non-volatile nature of QSPI FLASH, it can be used as a boot device for the
system to store the boot image of the system. These images mainly include
FPGA bit files, ARM application code, and other user data files. The specific

PS system clock source
The ZYNQ chip provides a 33.333MHz clock input to the PS section via
the X4 crystal on the FPGA core board AC7Z035B. The input of the clock is
connected to the pin of the PS_CLK_500 of the BANK500 of the ZYNQ chip.
The schematic diagram is shown in Figure 2-6-2:

PL system clock source
The differential 200MHz PL system clock source is provided on the FPGA
core board AC7Z035B for the reference clock of the DDR3 controller. The
crystal output is connected to the global clock (MRCC) of the FPGA BANK34,
which can be used to drive the DDR3 controller and user logic in the FPGA.
The schematic diagram of the clock source is shown in Figure 6-3

GTX reference clock
The FPGA core board AC7Z035B provides a 125Mhz reference clock for
the GTX transceiver. The reference clock is connected to the reference clock
input of the BANK111, REFCLK1P/REFCLK1N. The schematic diagram of the
clock source is shown in Figure 6-4.

Part 7: LED Light
There are 3 red LED lights on the AC7Z035B FPGA core board, one of
which is the power indicator light (PWR), one is the configuration LED light
(DONE), and one is the user LED light. When the core board is powered, the
power indicator will illuminate; when the FPGA is configured, the configuration
LED will illuminate. The user LED light is connected to the IO of the PL. The
user can control the light on and off by the program. When the IO voltage
connected to the user LED is high, the user LED is off. When the connection IO
voltage is low, the user LED will be lit. The schematic diagram of the LED light
