Abstract
A system and method to generate a clock domain-independent abstract of a component in an integrated circuit design. The method includes performing an initial analysis of the component using an initial clock value for each clock domain type, the clock domain types including a functional clock and a test clock, executing an abstractor to obtain a reduced order model of the initial analysis as a clock domain-dependent abstract, and obtaining original constraints associated with one or more circuit elements within the component from the clock domain-dependent abstract. Generating generalized constraints is based on clock domain-dependent constraints among the original constraints, and generating the clock domain-independent abstract is based on the generalized constraints. The method also includes obtaining a physical implementation based on one or more analyses using the clock domain-independent abstract.
