Optimal simplification of constraint-based testbenches

摘要

Methods and systems are provided for determining redundancies in a system model such as a complex circuit design including gates that are state components. A candidate redundant gate is selected, and a merged model is built that eliminates the candidate redundant gate. If the candidate redundant gate is within the merged constraint cone the pre-merge model is used to validate redundancy of the candidate redundant gate. However, if the candidate redundant gate is not within the merged constraint cone the merged model is instead used to validate redundancy of the candidate redundant gate.
