Data-driven cutout for mixed transistor-level and abstract-based timing analysis

A computer system for supporting cutout variations within transistor-level and abstract-based timing analysis, the computer system comprises:

• a memory;
• and
• a processor in communication with the memory, the processor being configured to perform operations to:
• specify a plurality of rules to parameterize a small kernel pattern;
• specify one or more post-matching rules for joining the small kernel pattern matches into a full-size cutout match;
• generate a plurality of timing rules for each of a specific type of a kernel;
• identify one or more repetitive structures and/or symmetries within the small kernel pattern match;
• stitch the small kernel matches;
• compose the stitched small kernel matches with a correct pin correlation to a cutout;
• and
• determine the kernel timing for the composed stitched kernel matches, based on the generated timing rules.
