Method and system for optimized automated case-splitting via constraints in a symbolic simulation framework

摘要

A method for performing verification is proposed. The method comprises receiving a design and building an intermediate binary decision diagram for the design containing one or more nodal binary decision diagrams. In response to a size of the intermediate binary decision diagram exceeding a size threshold, a node of the design is selected for case-splitting. A first case-splitting is performed upon the selected node of the design to generate a primary constraint for setting the selected node to a primary value. A first constraining is performed on one of the one or more nodal binary decision diagrams with the primary constraint to generate a primary final binary decision diagram, a first verification of the design is performed using the primary final binary decision diagram.
