Adaptive characterization and instantiation of timing abstracts

A computer program product for adaptively characterizing and instantiating timing models to perform timing analysis of an integrated circuit, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to perform a method comprising:

• generating an adaptable timing model for one or more macro models of a macro, the macro including two or more primitives of a component of the integrated circuit, the adaptable timing model being a parameterized timing model with at least one aspect represented by two or more models;
• estimating requirements for the timing analysis, the requirements including accuracy, runtime, or memory requirements;
• and
• selecting a specific timing model obtained by setting parameters of the adaptable timing model to perform the timing analysis based on the requirements;
• determining an error function associated with each of the aspects of the adaptable timing model for each of the specific timing models obtained from the adaptable timing model, wherein the determining the error functions associated with each of the aspects of the adaptable timing model includes determining the error functions for each path starting at each input of the macro and a result of performing the timing analysis is used to manufacture the integrated circuit.
