Abstract: The present disclosure describes a method for detecting unacceptable connection patterns. The method includes, using a processor to perform at least one of: performing an automated place-and-route (APR) process on a circuit layout that includes a first standard cell without a marker layer to generate a circuit graphic database system (GDS) file from the circuit layout, generating a standard-cell GDS file that includes a second standard cell with at least one marker layer applied to the second standard cell, and merging the circuit GDS file with the standard-cell GDS file to generate a merged GDS file that includes the first standard cell with at least one marker layer based on the second standard cell. The method further includes determining whether a connection pattern of the first standard cell in the merged GDS file is an unacceptable connection pattern.
