Abstract
Some embodiments provide a system that improves performance during parameterized cell instantiation in an electronic design automation (EDA) application. During operation, the system persists evaluation results associated with a parameterized cell in the design within a session of the EDA application so that the evaluation results are available even after they have been flushed from memory. Further, the system can persist the evaluation results across sessions of the EDA application. Next, the system uses the persisted evaluation results to instantiate the parameterized cell without re-evaluating the parameterized cell. Finally, the system discards the persisted evaluation results based at least on a dependency associated with the parameterized cell.
