12.1 PlanAhead - Error on constraints when running Implementation in PlanAhead points to merged UCF

描述

Problems can arise if a user has multiple UCFs and NCFs in their design with the top-level UCF marked as the target, and then attempts to implement.

If there is an error in the UCF file that is generated by merging all the NCFs and UCFs, the error navigation points to the top.ucf in the sources directory rather than the generated top.ucf in the impl_1 directory in which the error actually resides.

解决方案

The message has been improved in the ISE Design Suite 12.2 release to point to the correct ".ucf" that contains the error.

In ISE Design Suite 12.2, you can go into the impl_1 directory that has the merged ".ucf" to correct the error.
