When I run NGDBuild, the following warning occurs when using LVDS 33 I/O Standard with DIFF_TERM constraint:
"WARNING:NgdBuild:486 - Attribute "DIFF_TERM" is not allowed on symbol "<name>" of type "IPAD". This attribute will be ignored."
Will this constraint still be applied to the element?
The message is incorrect and constraint will be applied correctly. This messaging problem will be fixed in ISE version 11.1.
