12/31/2022, 12:05 PMHello everyone, I am facing a couple of issues regarding openlane. 1. I was trying to build a design directly in the wrapper but the issue is that during detailed routing the design takes so much RAM when it runs out of RAM it fails the design. Upon google the issue I found an open issue on github where same problem happened. The suggestion there was to turn fill insertion off. This results in DRC errors at the end of n-well spacing. I wanted to know that is there any way around the issue except increasing the RAM. The design was arounf 10K cells only still more than 15 GB of RAM was required to route.
