Problem Title:
Men2XNF8/ENWrite error: "Pin does not map to a net in model" due to
incorrect COMPMC16 macro



Problem Description:
Keywords: men2xnf8, enwrite, compmc16

Urgency: Standard

While processing an XC5200 design in which the COMPMC16 macro is used,
Men2XNF8 may halt in ENWrite with the following:

   // Error: Pin B(8) (P$26) of instance /PH, part $LCA/xc5200/compmc16/part,
   model $LCA/xc5200/compmc16/schematic does not map to a net in model (from:
   DDMS/EDDM/EDDM Connectivity 15)

The error message applies to pins A(8)-A(15) and B(8)-B(15).

This is caused by mislabeled busses in the COMPMC16 macro in the XC5200
library.  The bus ports on the COMPMC16 symbol are labeled A(15:0) and
B(15:0), but the underlying busses are labeled A(7:0) and B(7:0).  Also,
the two busses are bus-ripped improperly in the underlying schematic.


Solution 1:

A corrected version of COMPMC16 is available:

   (Xilinx File ftp://ftp.xilinx.com/pub/swhelp/mentor/c16men5k.tar.Z)

This is a compressed TAR file that needs to be extracted in the $LCA/xc5200
directory.
