  • METHOD OF CONTEXT-SENSITIVE, TRANS-REFLEXIVE INCREMENTAL DESIGN RULE CHECKING AND ITS APPLICATIONS
    Publication number: 20120180014
    Abstract: A computer-implemented method to perform context-sensitive incremental design rule checking (DRC) for an integrated circuit (IC). An incremental DRC engine checks design rule violations between a set of environment shapes and a set of active shapes. If no design rule violations are found, the set of active shapes will be added into the set of environment shapes. Furthermore, the incremental DRC engine can be embedded into placement tools, routing tools, or interactive layout editing tools to check design rule violations and help generate DRC error free layouts.
