    Regarding debug, very few open source cores support anything approaching the kind of debug interface you would find on a microcontroller or vendor core (breakpoints, single stepping and memory viewers). Supporting these features involves considerable extra hardware and some special software to interface with GDB, called a GDB stub. The Bonfire CPU has support for a GDB stub but I've never tried it.
