50G Interlaken and 100G Interlaken MegaCore Functions Upgrade to Quartus II Software v13.1 With Default Data Rate

If you upgrade a 50G Interlaken IP core instance or a 100G Interlaken IP core instance from a version that predates the Quartus II software v13.1 release, to the 13.1 version, using either regeneration through the MegaWizard Plug-In Manager or the IP Upgrade tool, the data rate reverts to the default Data rate parameter value.

To work around this issue, after you regenerate or upgrade your 50G Interlaken IP core or 100G Interlaken IP core in the Quartus II software v13.1, edit the IP core instance in the 13.1 software, update the Data rate parameter to your desired Interlaken data rate, and regenerate.

This issue is fixed in version 14.0 of the 50G Interlaken MegaCore function and the 100G Interlaken MegaCore function.
