Abstract
In a system and method that simulates a design including a third party IP component, a driver for the IP component is compiled and executed in a workstation implementing the simulation platform for the design. The source code for the driver is modified to allow the simulation to reroute certain functions that would cause the simulator to hang until an event occurs that would unlock the simulation. The rerouting includes storing instruction location, state information, and any other context information needed to restore a paused function. The saved information is stored in a stack that is traversed upon detection of the event.
