Abstract

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.
