To generate a functional testbench for a RapidIO II IP core that targets an Arria 10 device, you must click Generate > Generate Testbench in the RapidIO II parameter editor. If you use a different method to try to generate the testbench, the parameter editor does not generate a working testbench.
This issue has no workaround. To avoid this issue, use the recommended method to generate your Arria 10 RapidIO II IP core testbench.
This issue will be fixed in a future version of the RapidIO II MegaCore Function User Guide.
