Abstract

Various embodiments provide for inserting an etching shape in a circuit design based on one or more spacing rules, which can be part of electronic design automation (EDA). Some embodiments described herein address wire-end spacing violations for abutted cell placements by enabling one or more etching shapes to be inserted during block implementations, without needing to insert the etching shape at a top level of a circuit design. Additionally, some embodiments described herein address violations of one or more height rules by supporting variable trim height while ensuring that no new violation is introduced with a new etching shape.
