FPGA-blinky

this is a collection of templates (with Makefile) for different FPGA's and toolchains

all templates are generated by the https://github.com/multigcs/LinuxCNC-RIO project with an minimal configuration (blinking LED)

Boards:

• Alhambra-II (ice40hx4k)
• ICEBreakerV1.0e (ice40up5k)
• TangNano20K (GW2AR-LV18QN88C8/I7)
• TangPrimer20K (GW2A-LV18PG256C8/I7)
• arty-a7-35t (xc7a35ticsg324-1l)
• Colorlight5A-75E (ecp5-25K)
• Colorlight_i5-v7.0 (ecp5-25K)
• Lattice-ICE40HX8K (ICE40HX8K)
• Olimex-ICE40HX8K-EVB (ICE40HX8K)
• TangNano9K (GW1NR-LV9QN88PC6/I5)
• TinyFPGA-BX (ice40lp8k)
• Cyclone IV FPGA EP4CE6E22C8N Development Board USB V2 (EP4CE6E22C8N / Cyclone IV)
• Open Bench Logic Sniffer (xc3s250e / Spartan-3E)
• Bugblat PIF_2 (LCMXO2-7000HC-5TG144C)

Toolchains:

• yosys/nextpnr
• gowin
• ISE/Webpack
• quartus
• Vivado
• Diamond

quick-start

add the toolchain to your system PATH, in my case:

export PATH=$PATH:/opt/oss-cad-suite/bin/
export PATH=$PATH:/opt/Xilinx/Vivado/2023.1/bin/
export PATH=$PATH:/opt/gowin/IDE/bin/
export PATH=$PATH:/opt/intelFPGA_lite/22.1std/quartus/bin/
export PATH=$PATH:/opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/
export PATH=$PATH:/opt/diamond/3.12/bin/lin64/

go into the target directory and run make:

cd EP4CE6E22C8/
make

build times

this is only a small comparison, it is not very meaningful and varies depending on the system and project
