All opinions are, obviously, my own and not necessarily shared by any employer in the past, present, or future.
I recently implemented fast (30-40 MB/s) USB communication between an FPGA board (Digilent’s CMOD A7, based on a Xilinx Artix-7 FPGA) and a host PC. This uses the FT245 synchronous FIFO mode of an FTDI FT232H or similar. I’m using Verilog (technically SystemVerilog, but for this I’m using very little syntax that is not also …
My C64 devkit project interfaces to the actual C64 hardware by replacing the main memory. It’s unlikely I’ll get it working perfectly correctly first time, and even if it appears to work, I need to verify it. While I can debug issues by using a logic analyser and checking timing, it’s a fairly long winded …
