Problem Title:
XC3000A: Map ignores LOC on pads driving BUFG
Problem Description:
Urgency: standard
Desrciption: for 3kA designs, Map ingores attempts to LOC an input pad which drives a BUFG to the de
sired TCLKIN or BCLKIN pin.
Solution 1:
Workaround: Instantiate either a GCLK or ACLK buffer instead of the generic BUFG clock buffer to for
