Abstract
A computer-implemented method for debugging the power aspect of an IC design by integrating the power specification expressed in certain power specification format and its corresponding circuit design within a power schematic diagram called power map. Power map is created by using a power data base generated by regrouping the original circuit design hierarchy to new hierarchies defined by the power specification. Power map contains power cell symbols (such as isolation cells, level shifters, power switches) and signal nets, and can show the relationship between power domains. Power map can also display mismatches or errors between the power specification and the circuit design for those signals connecting the power domains. Furthermore, power map can be used in conjunction with simulation result.
