Analyze Simulation Results
Inspect data using cursors and custom visualizations, replay simulation results, compare simulation data
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.
