Hello, I am trying to tapeout my (first) MPW-8 submission and have a tapeout error. https://platform.efabless.com/shuttles/MPW-8/project/1868 It passed precheck, tapeout build, and first 5/6 checks, then fails w/ an FOM Density Check: .. STDOUT: {{Step Update}} Executing Check 5 of 6: Klayout Metal Minimum Clear Area Density on [caravel_000811c9.oas] STDERR: [ WARN ] MET Density Check Result: 'caravel_000811c9.oas' has 0 DRC violations. STDOUT: {{Step Update}} Executing Check 6 of 6: Klayout Field Oxide Mask Density on [caravel_000811c9.oas] STDERR: [ WARN ] FOM Density Check Result: 'caravel_000811c9.oas' has 25 DRC violations. I've attached a photo of the DRC check that fails. Any advice or pointers on how to fix this problem would be appreciated. Thank you.

Check the tap and diff in the regions listed. Does it appear to be more than 67% covered? Fill layers are also included, so you could check the

tapeout/outputs/oas/caravel_<user_id>.oas

file too.

Perhaps this occurs because I have set GPL_CELL_PADDING/DPL_CELL_PADDING to zero to squeeze in more bits/mm2?

perhaps.
