Internal Error: io_obuf_iterm->is_inverted() == comp_obuf_iterm->is_inverted()

Description

The above internal error may appear when you design a custom memory interface with the ALTDQ_DQS MegaCore®. The internal error is caused by inconsistent output enabling assignments on the DQS and DQSn signals.

Resolution

Make sure you have the same assignments on both DQS and DQSn signals.
