View pruning for routing tree optimization

Abstract:

Electronic design automation systems, methods, and media are presented for view pruning to increase the efficiency of computing operations for analyzing and updating a circuit design for an integrated circuit. One embodiment involves accessing a circuit design stored in memory that is associated with a plurality of views, selecting a first view of the plurality of view for view pruning analysis, and identifying a plurality of input values for the first view of the plurality of views. Random nets are generated based on the views, view inputs, and pruning thresholds. Certain views are then selected as dominant based on a comparison of the output slews different nets and views. Subsequent analysis is then performed and used to update the design without using the pruned views (e.g., using the selected dominant views).
