6.4.1 Simulation

The following steps describe how to simulate the core using the testbench:

  1. Open the Libero SoC application, click Libero SoC Catalog tab, expand Solutions-MotorControl
  2. Double-click Median Filter, and then click OK. The documentation associated with the IP are listed under Documentation.
    Important: If you do not see the Catalog tab, navigate to View Windows menu and click Catalog to make it visible.

  3. On the Stimulus Hierarchy tab, right-click testbench (median_filter_tb.v), point to Simulate Pre-Synth Design , and then click Open Interactively.
    Important: If you do not see the Stimulus Hierarchy tab, navigate to View > Windows menu and click Stimulus Hierarchy to make it visible.
