17.4.1 Simulation

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

Open Libero SoC Catalog tab, expand Solutions-MotorControl, double click SVM, 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.

On the Stimulus Hierarchy tab, select the testbench (svm_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.

Important: If the simulation is interrupted due to the runtime limit specified in the .do file, use the

run
                -all

command to complete the simulation.
