Critical Issue
Description
In the MegaWizard Plug-In Manager design flow, generation of any RapidIO IP core variation that targets a Stratix IV device hangs, unless your installation includes Arria II GX support.
Resolution
To avoid this issue, ensure that you include support for Arria II GX devices in your Quartus II software installation.
This issue will be fixed in a future version of the RapidIO MegaCore function.
