Abstract

Techniques improve integrated circuit design by employing multi-operating condition frequency prediction for statically timed designs through statistical analysis. A design management component (DMC) can determine a trained model representing timing path properties and operating conditions of agnostic timing paths based on an analysis of vectorized data that represents timing path information associated with the agnostic timing paths. DMC can perform statistical regression on the vectorized data to facilitate training the trained model. A static timing analysis (STA) component can perform STA on design information associated with the integrated circuitry design and determine an operating condition of a timing path of the integrated circuitry design based on the STA. DMC can predict or determine at least one other operating condition associated with the integrated circuitry design based on the operating condition and the trained model.
