always been a parameter here (since forever), defaults to 4 WAYS:
ah that's interesting, WAYS=2 on instantiation:
no evidence of it being selectable in the Makefile though (unless i have
misunderstood or am missing something)
which makes me curious as to the sky130a modifications by Anton which
briefly whizzed by my eyes and i recall the word "Makefile"
so no, as it stands, not a compile-time option aaiui, but the default is 2
WAYS, 64 SETS.
