Hello @mehdi, I get

NW.1b_3.3V

errors in the reference pad ring. I ran a subset of the rules in the DRC script found in the efabless/mpw_precheck repository, with

CONNECTIVITY_RULES

enabled. https://github.com/efabless/mpw_precheck/blob/main/checks/tech-files/gf180mcuC_mr.drc

Clearly a false positive error. Ping @Amro Tork

@Farag Elsayed Could you please check this out?

@Alfonso Cortés This DRC rule deck exists in

mpw_precheck

looks old, please use DRC from here

@Tim Edwards Is it possible to update the

mpw_precheck

to the latest?
