 Or you can run a dual lock-step simulation, with one running a bit delayed from the the other one, and which will start recording the wave once the leading simulation had a failure.
 
-To do this, you can use the DualSimTracer utility, which will ask you the compiled hardware, the window of time you want to capture the wave before falure, and a seed.
