AR# 10287

Description

General Description:-

Setting the constraint "NET <netname> FAST; " in the UCF file for an XPLA3 Webpack

project has no effect on the slew rate of the output.

Solution

Change the default Output Slew Rate option to "FAST" in the Implement Design -> Properties menu.

If you need any outputs with slow slew rate, add the "NET <netname> SLOW;" constriant to the

UCF file.

This will be fixed in WebPACK 3.3.
