Viewing Results With the Simulation Data Inspector

Why Use the Simulation Data Inspector

Using the Simulation Data Inspector to inspect and compare data after converting your floating-point model to fixed point facilitates tracking numerical error propagation.

When to Use the Simulation Data Inspector

Use the Simulation Data Inspector to:

  • Plot multiple signals in one or more axes

  • Compare a signal in different runs

  • Compare all logged signal data from different runs

  • Export signal logging results to a MAT-file

  • Specify tolerances for signal comparison

  • Create a report of the current view and data in the Simulation Data Inspector

What You Can Inspect in the Simulation Data Inspector

The Fixed-Point Tool uses the Simulation Data Inspector tool plotting capabilities that enable you to plot signals for graphical analysis. The tool can access signal data that resides in the MATLAB® workspace, allowing you to plot simulation results associated with:

  • Scope blocks whose Save data to workspace parameter is selected

  • To Workspace blocks

  • Root-level Outport blocks, when the Output check box on the Data Import/Export pane of the Configuration Parameters dialog box is selected

  • Logged signal data

    Tip   The Contents pane of the Fixed-Point Tool displays an antenna icon next to items that you can plot.
