4.1i Constraints Editor - When I open a new UCF file, an error is reported ("The .ngd file has a timestamp that is earlier than the .ucf timestamp...")

Description

General Description:

When I open a new UCF file, the following Constraints Editor error is reported:

"ERROR:Constraints Editor - /home/shiv/test/timing/E.9/test.ucf does not exist. Create?"

"WARNING:Constraints Editor - The .ngd file has a timestamp that is earlier than the timestamp for the UCF file."

No such ERROR/WARNING messages are reported in the D.22 Constraints Editor.

Solution

This problem will be fixed in the 5.1i software, which is scheduled to be released in September, 2002.
