@Tim Edwards@Matthew Guthaus@jeffdi I am facing 19 BEOL DRC violation inside the 2KB SRAM (sky130_sram_2kbyte_1rw1r_32x512_8). This memory picked from PDK. Look like new/update DRC rule is creating issue. Is there updated any SRAM available for latest PDK?
All the Violation are related to : via3.2 : min. via3 spacing : 0.2um

Is it really a DRC error or a problem with the rules?

(Which memory macro are you using? Which version of the 2kbyte...)

@Mitch Bailey This is Klayout DRC check and it's failing in local Pre-check Run's. My expectation it will fail in efabless tape-out check also.
Look like I have updated PDK 24th Oct and let me cross-check any new version is released.

@Mitch Bailey look like it's top-level power hook-up to SRAM is creating issue, let me review issue.
