P-CELL CACHING

摘要

In one or more embodiments, a caching apparatus includes functionality to persist evaluation results associated with pcells in a design across sessions of an EDA application as well as across design libraries. The caching apparatus may create and maintain a mirror cache in a design library with only subMasters referenced by the design library. The contents of a central cache file or a mirror cache in the design library are examined for an evaluation result. If the evaluation result is not found in the central cache file, the evaluation result may be retrieved from the mirror cache if present.

主权项

1. A method comprising:
persisting, using one or more computer systems, evaluation results associated with a parameterized cell in a design across libraries of an EDA application, which involves storing an evaluation result of a variant of the parameterized cell at a location in at least one of a central cache file or a mirror cache file in a design library; mapping, using the one or more computer systems, the variant to the location; and instantiating, using the one or more computer systems, the parameterized cell from either the cache file or the mirrored cache file when the cache file or the mirrored cache file contains the evaluation result.
