Xc9500:	The fitter report pinout does not match that of the data book


Problem Description:
Keywords:  9500, pinout

Urgency:  Standard

After compiling a 9500 design, you may notice that the fitter
report does not appear to match the expected pinout as stated

Book says they should be.
XABEL CPLD v6.1.2



Solution 1:

This can be caused by having more than one signal assigned
to the same pin.  The CPLD fitter will not give you a warning
that you have assigned 2 signals to one pin.

Check the source file for cases where more than one signal
drive a pin or are assigned to a pin.
