Urgency: Standard

General Description:

If you are targeting a Virtex design, and you have instantiated an output cell
with a non-LVTTL voltage standard, Foundation Express v2.1.2 will produce
an error in the optimization phase of synthesis.

Foundation Express 1.5 will report during optimize:

Internal Error: Invalid value '' for attribute
'pmap_slew' on ...... (FE-INTERNAL-padmap-2).
