Problem Title:
XC5200: XACT 5.2.1- xnfprep: Error 4708


Problem Description:
Urgency: Standard


Description

xnfprep: Error 4708: There are 23 Tbufs driving the signal.
The part 5200, only has 22 drivers available.


Solution 1:


The number of Tbufs that can be tied together is equal to the
number of CLB columns in the used device. For example, the
5202 has 8 columns therefore, only 8 tristate buffers
maybe tied together.
