by the way the dont use variable needs escaped ” on my platform does it work as is for you?

It works for me in gf12lp

maybe is just the way the .lib is written

Opening file for replace: objects/sw130/copperv/merged.lib.tmp
(^\s*cell\s*\(\s*("sky130_fd_sc_hs__dlymetal6s6s_1"|"sky130_fd_sc_hs__buf_2"|"sky130_fd_sc_hs__clkbuf_4"|"sky130_fd_sc_hs__dfxtp_1")\)\s*\{)
Marked 4 cells as dont_use

From .lib

cell ("sky130_fd_sc_hs__buf_2") {

So from how the pattern was defined, it was expecting the quotes to be passed, if I don’t escape them, they get lost in the make assignment

I think that needs to be removed from .libs

maybe is better to add something like [“]+ to the pattern

I just checked versus other commercial pdks and there are no quotes

I meant to fix it on util/markDontUse.py to make it more robust

pattern = r"(^\s*cell\s*\(\s*("+"|".join(patternList)+")\)\s*\{)"

I checked on my end and I see both ways w and wo “, even on production libs.

okay I will make that chnage

more like:

pattern = r"(^\s*cell\s*\(\s*([\"]*"+"[\"]*|[\"]*".join(patternList)+"[\"]*)\)\s*\{)"
