EMIF Toolkit Error May Occur for Multiple Interfaces in the Same Column with the Same Interface ID

On Arria 10 devices, regardless of memory protocol, an internal error may occur in the EMIF Toolkit if multiple EMIF instances in an I/O column have the same interface ID.

The workaround for this problem is to assign a different interface ID to each EMIF instance prior to IP generation; you can do this on the Diagnostics tab of the parameter editor. EMIF instances without the debug interface enabled should also be given unique IDs; to do this, temporarily enable the debug interface, change the interface ID, and then disable the debug interface.

This problem will be fixed in a future version.
