Abstract

A method and system are disclosed that utilize the expressiveness of hardware description languages for providing comprehensive runtime monitoring during hardware accelerated simulation of a digital circuit design. According to the present invention a design entity forming part of a digital circuit design that will be translated and assembled into a simulation executable model, is described utilizing a hardware description language. Next, an instrumentation entity designed to send a failure signal in response to detecting an occurrence of a failure event within the simulation executable model is described utilizing the same hardware description language. Thereafter, a simulation test is initiated on the simulation executable model utilizing a hardware simulator. Finally, during the simulation test, and in response to receiving a failure signal from the instrumentation entity, the simulation test is terminated such that the failure event may be efficiently identified and diagnosed.
