Abstract
Example systems and methods are disclosed for performing a timing analysis on a circuit design. A plurality of switching scenarios are identified for the circuit design. One or more predictive models are applied to predict a subset of the plurality of switching scenarios that are likely to cause timing paths with critical timing problems. A dynamic voltage analysis is performed on timing paths based on the subset of switching scenarios. The one or more predictive models are applied to predict a set of critical timing paths based on the subset of switching scenarios that are likely to cause critical timing problems, the one or more predictive models taking into account the dynamic voltage analysis. A timing analysis is the performed on the set of critical timing paths.
