I have some old chips and in light of the shortages I continually see despite the 52 week lead time thrown around in the summer of 2020, I would like to develop with them. Specifically, I am talking about Spartan 3E parts and would like to know about setting up a stable toolchain with Win10 or 11. This could include Ubunutu 20.04 on WSL2. Does anyone have a decent recipe to develop these chips. My last development of FPGA was on a custom development board and I utilized a make file calling the necessary tools to create the binary from the ISE tools:
rem Makefile to compile and download a simple VHDL program
rem program.ngc: fpga.vhd echo run -ifn fpga.vhd -ifmt VHDL -ofn program -p xc3s100e-4-vq100 -opt_mode Speed -opt_level 1 | xst
rem program.ngd: program.ngc fpga.ucf ngdbuild -p xc3s100e-4-vq100 -uc fpga.ucf program.ngc
rem program.ncd: fpga.ngd map -detail -pr b program.ngd
rem parout.ncd: program.ncd par program.ncd parout.ncd program.pcf
rem load_program.bit: parout.ncd bitgen -g StartUpClk:CClk -g CRC:Enable parout.ncd load_program.bit program.pcf
rem load_program.bin: load_program.bit promgen -w -p bin -o load_program.bin -u 0 load_program.bit
Thank you for your consideration,
