are you a platform/embedded developer?
do you need to interact with hardware in a semi-custom manner?
would you like to suffer a lot less doing it?
if so, #GlasgowInterfaceExplorer might be for you. the code below is all you need to build a custom testbench for a DUT you've never seen before. just as easily you can add JTAG/SWD debug, protocol analyzers, etc.
