AR# 30367 10.1 Constraints Editor - DDR OFFSET IN/OUT Wizard uses FALLING keyword for both rising and falling edge elements, and the pad timegrp name includes extra letters

Description
Solution

Keywords: DDR

After creating either OFFSET IN or OFFSET OUT constraints using the input/output DDR Wizard, both the rising and falling edge elements include the FALLING keyword instead of RISING and FALLING. Also, the pad timegrp name is "orTNMorTPSYNC<grpname>".

To work around this issue, manually edit the UCF.

This problem has been fixed in the latest 10.1 Service Pack available at:
http://www.xilinx.com/support/download/index.htm
The first service pack containing the fix is 10.1 Service Pack 1.
