Abstract
Methods are provided to facilitate automated creation and management of design rule checking or DRC waiver descriptions. Embodiments include receiving a plurality of first checksums corresponding to respective first geometric element violations waived in association with a block of an integrated circuit design, the first checksums being based on a first version of at least one design verification rule and/or of the block, receiving a second checksum corresponding to a second geometric element violation associated with the block, the second checksum being based on a second version of the design verification rule and/or of the block, determining whether the second checksum corresponds to at least one of the first checksums, and, if the second checksum does not correspond to at least one first checksum, generating a waiver request for the second geometric element error.
