2.1.1. Generating the Testbench

  1. On the Generate menu, select Generate Testbench System. Specify the parameters listed in the following table.
    Table 6.  Parameters to Specify on the Generation Tab in Qsys

    Parameter

    Value

    Testbench System

    Create testbench Qsys system

    Standard, BFMs for standard Qsys interfaces

    Create testbench simulation model

    Verilog

    Allow mixed-language simulation

    Turn this option off

    Output Directory

    Testbench

    <working_dir>/pcie_de_gen1_x8_ast128/testbench

  2. Click the Generate button at the bottom of the Generation tab to create the testbench.

    This testbench assumes that you are running the DMA application that the example design available in the installation directory creates. Otherwise, the testbench tests will probably fail unless your own testbench has equivalent functionality.
