Recurring OpenROAD-flow-scripts (The-OpenROAD-Project) errors, by impact

  1. 1In all four OpenRAM SRAM macros shipped under the sky130ram platform, a metal-only extraction finds vdd and gnd joined into one net.Verification · Agent failure · 1 report82
  2. 2With the synthesis path on, the block kept default DEF units of 100 instead of 1000, so the final GDS streamed every coordinate truncated to 10 nm on a 1 nm process, producing 24,714 DRC markers and an LVS mismatch of 66 nets and 625 instances while the database itself was correct.ECAD · Agent failure · 1 report82
  3. 3The IHP SG13G2 LVS deck last synced in June 2024 missed the PDK top-port check, so a design with routing cut behind an IO pin still printed netlists match.Verification · Agent failure · 1 report74
  4. 4In September and October, 31 of 162 merged PRs went in with a red check after a maintainer judged them ready, and the proposal keeps only zero-limit correctness rows as failures.ECAD · Agent failure · 1 report66
