Show HN: JPDB, GDB for Your Waveforms
hey everyone, I've been working on JPDB is a GDB like debugger for
waveforms. if you give JPDB a waveform* and some other information,
then you can step through the program that was executed when that
waveform was created. i say GDB-like because JPDB has it's own GDB
client (its called shucks), that implements the client side logic
of the GDB protocol faithfully, but doesnt have all of the GDB
niceties (like python integration, etc). this allows the project to
be specialized on debugging waveforms specifically, when compared
to another approach like connecting to a gdb client JPDB
integrates with the waveform viewer surfer (https://surfer-
project.org/), so you can look at other signals there. this is
still ongoing because the underlying protocol (WCP) is a little
Fresh if you're developing your own CPU, give it a shot.
Superscalar designs arent supported yet but it would be pretty
straightforward, just give me your waves ( i am touching my fingers
together villainously as i type this) and i will make it happen
also if you want to use system with a "normal" gdb client, the dang
library presents a gdbstub server, so you can run that and connect
to it. here's a demo but it should work on your local machine if
you follow the readme: https://www.youtube.com/watch?v=EOo1aG_wcJg
