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