5.24.28 Selecting a Stimulus File for Simulation

Before running simulation, you must associate a testbench. If you attempt to run simulation without an associated testbench, the Project Manager asks you to associate a testbench or open ModelSim without a testbench.

To associate a stimulus:

1. Run simulation or right-click the top level module in the Hierarchy Menu and select Organize Stimulus File

   from the right-click menu. The Organize Stimulus dialog box appears.

   1. Associate your testbench(es):

In the Organize Stimulus dialog box, all the stimulus files in the current Libero IDE project appear in the left Stimulus Files in the Project list box. Files already associated with the block appear in the Associated Files list box.

In most cases you will only have one testbench associated with your block. However, if you want simultaneous association of multiple testbench files for one simulation session, as in the case of PCI cores, add multiple files to the Associated Files dialog box.

To add a testbench: Select the testbench you want to associate with the block in the Stimulus files in the project list box and click

Add to add it to the Associated Files list.

To remove a testbench: To remove or change the file(s) in the Associated files list box, select the file(s) and click Remove.

To order testbenches: Use the up and down arrows to define the order you want the testbenches compiled. The top level-entity should be at the bottom of the list.

1. When you are satisfied with the Associated File(s) list, click OK. A checkmark appears next to WaveFormer Pro in the Project Flow window to let you know that a testbench has been associated with the block.
