In the Simulation Data Inspector tool, you can use the Compare Signals tab to compare the same signal from two different simulation runs. To compare two data runs for a signal:
Open the Simulation Data Inspector tool. See Open the Simulation Data Inspector Tool.
Select the Compare Signals tab. By default, the Signal Browser table on the Compare Signals tab displays a row for each signal data, organized by simulation runs. For more information on modifying the Signal Browser table, see Customize the Simulation Data Inspector Interface.
Specify the Line Configuration for the signals that you are comparing.
To change the relative tolerance and absolute tolerance, add the Rel Tol and Abs Tol columns to the Signal Browser table. Double-click the corresponding fields for a signal and type in a value.
In the Sig 1 column, click one signal from the first simulation run for plotting. In this column, you can select only one signal.
In the Sig 2 column, click a signal from another simulation run for plotting. In this column, you can select only one signal.
Once two signals are selected, the Signals graph displays the signal data and the Difference graph displays the difference and tolerance values.
For information on manipulating the graphs, see Customize the Simulation Data Inspector Interface.
To create a report of the results, see Create Simulation Data Inspector Report.
