Xilinx-XCZ7Z010 core board

Project Description:
The Xilinx-XCZ7Z010 core board
is used for debugging FPGA network management devices
and can be used for small-size terminal network control
hardware configuration:
FPGA: XC7Z010/XC7Z020
; Memory: Low-power DDR3L, 8Gbit (2GB)
; Storage: eMMC5.0-8GB/NOR-FLASH-25Q64/EERROM-24C02/External TF Card;
Network Card: RTL8211E;
Open Source License
: CC-BY-NC-SA-3.0.
Project Attributes:
This project is being publicly disclosed for the first time and is my original work. This project has not won any awards in other competitions.
Project Progress
: Schematic Design: Completed;
PCB Design: Completed;
Soldering and Assembly: Completed;
Basic Function Debugging: Completed. (Power supply test and crystal oscillator frequency test, network port, USB, serial port, HDMI, TF-CARD)
Design principle
: Power supply section: The power supply scheme uses EA3059, 4-channel 2A-DC-DC, improving the integration of the power supply section.

Notes: When placing a sample order, select the necessary parameters: board material FR-4, 6-layer board, 1.6MM board thickness, impedance control select JLC06161H-3313 impedance structure, impedance control error 20%, other default parameters are fine. The sampling rules for this board support free sampling of JLC 6-layer boards. FLASH storage: For the EMMC section, if the EMMC used is eMMC5.0, R45 and R46 pull-down resistors need to be soldered. For other EMMC models, these two resistors do not need to be soldered. The memory chips must use DDR3L and the total capacity must not exceed 2GB (exceeding this will not be recognized). The filter capacitors on the board must be MLCC capacitors, not ceramic capacitors, otherwise it is easy to cause instability and crashes. The ZYNQ's main frequency crystal oscillator is an active crystal oscillator; please do not use a passive crystal oscillator. Note that the power supply chip must be EA3059, not EA3059C. The EA3059C only has 3 DC-DC converters.
