12.4.1 Simulation

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

  1. Open Libero SoC Catalog tab, expand Solutions-MotorControl, double click Resolver Interface, 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.

  2. On the Stimulus Hierarchy tab, select the testbench (resolver_interface_tb.v), right click and then click Simulate Pre-Synth Design > 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.
