US 12,762,315 B2 · Identifying potential improvement opportunities for simulation performance of an integrated circuit design

Abstract

Techniques for improved analysis and simulation of an IC design are disclosed. Simulation activity for an integrated circuit (IC) design is identified using one or more processors. One or more potential improvements to a simulation of the IC design are generated based on the simulation activity, the one or more potential improvements relating to at least one of signal activity or process activity, during simulation, reflected in the simulation activity. A hardware description language (HDL) design file corresponding to the IC design is modified to indicate the one or more potential improvements to the simulation.
