General Description:
In my UCF file, the FROM:TO constraint is not taking precedence over the NET OFFSET constraint as it should.
This occurs because the MAXDELAY constraint contains a superset of the offset constraint -- a strict intersection, as discussed in (Xilinx Answer 9297). Therefore, the precedence cannot be applied because the MAXDELAY constraint cannot be extracted from the offset constraint.
This will be fixed in the next major software release (after 5.1i).
