Why do my Interlaken 50G / 100G settings change when auto-upgrading the IP core?

Description

Due to a problem with the Interlaken IP Core, you will see parameter settings changed after IP upgrade.

This is due to the parameter values stored in .qsys or .ip files getting incorrectly overwritten to default when IP upgrade happens.

Resolution

To work around this problem, after IP upgrade open the Interlaken IP GUI and ensure parameters are correct for the required configuration.

This problem has been fixed in Intel® Quartus® Prime version 18.0.
