Inspect and Analyze Simulation Results

Inspect and compare simulation results to validate model designs using the Simulation Data Inspector

You can use the Simulation Data Inspector to inspect and compare data from multiple simulations. For example, you can check to see if the difference between two signals is within a certain design tolerance. To learn more, see Simulation Data Inspector in Your Workflow.
