3.1i Constraints Editor Missing USELOWSKEWLINES constraint for Spartan-II

Description

General Description:

In Constraints Editor, under the Advanced tab, there is

no button to identify nets for use of the Low Skew

Resources in the device.

解决方案

The workaround is to manually edit the ucf file to have

the following:

NET "my_net" USELOWSKEWLINES;

This is suppose to be fixed in the next major release

of the software.
