Some of my “useful bits” of library code have lived in
libv.vhd for a while – I’ve split it off and licensed it with a CC0 license (which means the author disclaims copyright and offers no warranty). It’s on github and I’ll add contributions from anyone who has any!
Either individual functions to add to
libv.vhd or great big wodges of useful code (like Jim Lewis’ randomized testing libraries maybe….)
