1.5i Ngdanno - ERROR:baspp - this design contains logic for which correlated back
annotation ...
Problem Description:
ERROR:baspp - this design contains logic for which correlated back annotation
is currently not supported. Please rerun ngdanno without using the .ngm file.
The test case has an ADD-G-CI COUT0 pin driving both an OBUF and an FMAP. The mapper packs the FMAP
into the same CLB as the ADD-G-CI (it was *not* directed to do this by user constraints) so the COU
T0 signal is routed through the G LUT, out the Y pin, and back into the F1 pin.
Solution 1:
A fix for this problem is included in the 1.5i Service Pack 1. For details
