  • How-to debug internal FPGA Logic with the $50 Openbench Logic Sniffer.

    This tutorial shows how to use the $50 OpenBench Logic Sniffer to debug internal FPGA logic. Debugging internal FPGA logic can be pretty challenging and time consuming, a lot can be done using simulation but when you have logic that interacts with the outside world debugging can come to a grinding halt. The traditional solution…
