CoRe-ECO: Concurrent Refinement of Detailed Place-and-Route for an Efficient ECO Automation

With the relentless scaling of technology nodes, physical design engineers encounter non-trivial challenges caused by rapidly increasing design complexity, particularly in the routing stage. Back-end designers must manually stitch/modify all of the design rule violations (DRVs) that remain after automatic place-and-route (P&R), during the implementation of engineering change orders (ECOs). In ...
