12.1 PlanAhead - Constraint changes made in the Implemented Design view are not passed to the "impl_1\.ucf"

Description


I load the netlist design and make some constraint changes in the Implemented Desgin Environment, and re-implement the design, but none of the constraint changes I made are being applied.
Why does this occur?

Solution


This is a known issue in the PlanAhead software.
If the Netlist Design is loaded and constraint changes are made in the Implemented Design environment, they are not passed to the < design >.ucf. If the Netlist Design is not loaded, the new constraints appear in the < design >.ucf as expected.
This has been fixed in the 12.2 release of the PlanAhead software.
