System and method enabling circuit topology recognition with auto-interactive constraint application and smart checking

摘要

A computer-implemented method of identifying sub-circuits in circuit designs includes: receiving a selection of a sub-circuit; specifying a match expression for the sub-circuit, where the match expression characterizes matching properties of components of the sub-circuit; modifying the match expression to change the matching properties of components of the sub-circuit; and producing an information structure in a computer readable medium, where the information structure associates a graph representing a topology of the selected sub-circuit with the modified match expression. Subsequently, the information structure corresponding to the selected sub-circuit can be identified in a given circuit design.
