CPArti: Artix-7 FPGA Development Board

A fairly low-cost 4-layer AMD/Xilinx Artix-7 FPGA development board with bidirectional and unidirectional high-speed signals, SRAM, DAC and USB-C connection with built-in JTAG programmer. Designed for JLC04161H-7628 layer stackup in KiCad. All available components include JLCPCB parts numbers for assembly. The project includes KiBot configuration for documentation and production files generation automation.

The development board includes:

Artix-7 FPGA
USB-C connection to the FPGA via FTDI USB to JTAG (no need for additional external programmer) + optional JTAG for a programmer (in case of USB connection failure)
2 unidirectional input and 3 unidirectional output SMA connections to FPGA
1 direct bidirectional SMA connections to FPGA
2 switched bidirectional SMA connections to a single FPGA pin (controlled from FPGA)
additional SRAM (4Mb)
high-speed DAC and op-amp for waveform generation implementation
separate programmable delay line (delay value selected via DIP switches)
24 MHz FPGA clock
8-digit 7-segment (+ decimal point) displays with MAX7219 display driver
14 programmable LEDs
8 programmable push buttons (deglitched)
8 programmable slide switched
powered via USB-C or separate 5.5mm DC barrel jack connector

FTDI USB to JTAG configuration

The built-in FTDI FT232H chip can be used instead of AMD/Xilinx programmer in Vivado Hardware Manager. The FTDI device needs to be configured using Vivado's program_ftdi utility. Refer to the Programming FTDI Devices for Vivado Hardware Manager Support for details.

KiBot automation

JLCPCB.kibot.yaml

The KiBot config to automatically generate production files:

Gerber files
drill files
BOM (Bill of Materials)
CPL (Component Placement List)

Usage:

kibot --schematic "CPArti FPGA dev board.kicad_sch" -c JLCPCB.kibot.yaml JLCPCB
