Abstract: Code coverage questions are addressed by a code coverage method that instruments an electronic module source design file with coverage probes and gives hierarchical names to the probes, then provides therefrom an instrumented gate level netlist. The instrumented netlist is run on a hardware emulator, executing reset trigger scripts to reset the branch and statement probes, and then a fully initialized design is driven in emulation on a simulated testbench from which the probe values are retrieved. These values can then be evaluated to determine the extent of code coverage. Various forms of coverage are supported including branch, statement, reset trigger and toggle coverage.
