Systems and methods for calculating common clock path pessimism for hierarchical timing analysis in an electronic design

Abstract:

The present disclosure relates to a system for use in electronic circuit design. The system may include a computing device configured to receive, using at least one processor, an electronic design. The at least one processor may be further configured to generate a common path pessimism removal ("cppr") database configured to store one or more cppr tags obtained from an initial timing analysis of at least a portion of the electronic design. The at least one processor may be further configured to apply the one or more cppr tags during a block-level timing analysis.
