4.1i Constraints Editor - When I change an IOSTANDARD from LVPECL to another type, the change is not implemented

説明

General Description:

I set the IOSTANDARD to LVPECL and write to the UCF; however, the UCF will keep that port set as LVPECL no matter what other information I enter in Constraints Editor. The constraint is then written to the UCF as "read-only", and I cannot change this in Constraints Editor.

ソリューション

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

Meanwhile, work around this issue by manually editing the UCF.
