Product Version: 1.5i

Problem Title:

1.5i, 2.1i 4K Map - Guided map of unchanged design is unable to guide several CLBs.


Problem Description:
A case has been seen where guided map is not able to guide 100%
of an unchanged design.

Guide mode: EXACT.
  90% of guide CLBs (29/32) were successfully guided.

These CLBs were NOT guided:
NCD comp STACKOP was NOT guided
NCD comp H5/QRESET was NOT guided
NCD comp H5/MUXBLK5/$Net00126_ was NOT guided

This problem is due to map being unable to successfully guide
"inverter/buffer trees" which have multiple connections on the same
signal using different signal names.


Solution 1:

A fix for this problem is scheduled for the release (as yet unnamed) following 2.1i.
