Progress notes

  • PDN hang issues https://github.com/The-OpenROAD-Project/OpenLane/issues/1173
  • Also discovered PDN hangs if extra lefs/defs are not deduplicated
  • with PDN set so dense, tapeout job fails with density checks
  • with unused PDN straps turned off, precheck fails
  • copied the erased version (just power rings) and deleted the first digital power rings, copy pasted that over final gds
  • precheck fails with missing power ports
  • manually added missing power ports to gl verilog of user_project_wrapper
