Emil J. Tywoniak dda22a35d1 dfflibmap: deduplicate liberty cell search code 2026-07-14 10:44:00 +02:00
Iztok Jeras 94d10012e7 dfflibmap: picking first instead of last cell with smallest area 
In a standard cell library cells are usually ordered from weakest to strongest.
Sometimes the two weakest cells have the same area.
Previously the stroner (last) of the two was selected,
now the weaker (first is selected).

simplemap: Moves $pmux mapping from techmap.v to simple map 
This Fixes the slow downs I observed in techmap.v, which we
attempted to fix via the simplify ast.h route originally. This
turned out to be rather complex though.

By moving $pmux to simplemap we can just avoid that code. My
test case now runs in 310s which is 40s faster than the baseline
change.
