5.1i PACE - PACE does not display the constraints I specified in the NCF or source code


Keywords: PACE, constraints, NCF, EDF, EDN, netlist, source, NGD

Urgency: Standard

General Description:
I specify constraints via the source code or NCF. The constraints are implemented, but PACE does not display them.


Although constraints specified via the source code or NCF will be passed to the NGD file, PACE will only read I/O standard specifications.

To work around this problem, specify all NCF and source constraints in the UCF file.

This issue will be fixed in the next major software release (after 5.1i).
