Abstract
A computer executable system and method analyzes a circuit design to extract a small set of signals for value collection using an emulator system. The collected signals are for specific purpose checkers such as assertions or interactive testbenches that are hard to emulate. A synthesizable monitor block is generated and added to the emulation environment to collect the signal value changes during emulation. The collected values are then used in localized logic simulation to perform the tasks that the original checkers intent to accomplish. This system leverages fast emulation speed and flexible logic simulation capabilities to perform the intended checker tasks much faster than using logic simulation alone.
