Please check out this repo. Thank you! I killed openlane during magic DRC to manually copy over the wrapper outputs. magic DRC took forever because the sram lef is not read in and there are thousands of errors. How should we modify the openlane flow? https://github.com/jake-ke/caravel_fast_ann_fieldious

Hi @Wajeh ul hasan, I think this turns out to be the same issue as Tim found in https://skywater-pdk.slack.com/archives/C016YSAP6TZ/p1654971517468939?thread_ts=1654867379.241259&cid=C016YSAP6TZ. I will try enforcing set_dont_use in Innovus.

I wonder why you are not using the dont use list from open pdks? It should include a big list of cells with known issues.

Hi Arman, I am using the dont use cells. I set them for DC, but it was my mistake that I did not know to set the dont use cells for Innovus again.
