Problem Title:
XSIMMAKE creates schematic symbols with double bounded bus pins.


Problem Description:
The Viewlogic simulation schematic created by XSIMMAKE has double bounded bus pi
ns on user created macros.  Such as: KA[3:0][3:0]

This is caused by the use of the $ARRAY= attribute in the schematic to array sin
gle net pin components to attach to buses.  For example: placing $ARRAY=4 on an
IBUF to make it into essentially an IBUF4.


Solution 1:

The $ARRAY attribute is not supported by the Xilinx/Viewlogic interface.
Do not use them.
