Comparing the simulation runs

ModelSim includes a Comparison Wizard that walks you through the steps of setting up a waveform comparison. You can also do it manually with menu or command line commands.

1. Select Compare > Comparison Wizard from the Wave or Main window.


2. Click the browse button and select gold.wlf as the Reference Dataset. Recall that this dataset is from the first simulation run prior to adding the 10 time unit delay.
   

Leave the Test Dataset set to Use Current Simulation, and then click Next.

3. Select Compare All Signals in the second dialog, and then click Next.
   


4. In the next three dialogs, click Next, Compute Differences Now, and Finish, respectively.
