Testbench System

Create testbench Qsys system—Creates a new testbench system that includes Avalon Verification Suite bus functional models (BMFs) for the exported interfaces. After generating this testbench system, you can open it in Qsys to view or modify the BFMs.
Create testbench simulation model—Allows you to generate a simulation model in Verilog or VHDL at the same time as the testbench system. Use this option if you want to use the Qsys-generated testbench system directly. If you want to make changes to the Qsys-generated system, open the testbench system in Qsys to make the changes and then generate a simulation model for that system.
Allow mixed-language simulation—Allows a mixed language testbench simulation model generation. If turned on, if a preferred simulation language is set, Qsys uses a fileset of the component for the simulation model generation. When turned off, which is the default, Qsys uses the selected language for the simulation model.
