XC5200: LCA2XNF v5.2.1 writes out 5-input logic gates for XC5200


Problem Description:
Keywords: LCA2XNF,  XC5200


Urgency: Standard

Description

There is a bug in LCA2XNF v5.2.1 where it will write out
5-input logic gates for an XC5200 design.  The maximum number
of inputs should be 4.

The bug may cause some 3rd party interfaces to fail to
translate designs for back annotation.


Solution 1:

Versions of LCA2XNF starting with v5.2.1j fix this problem. The new executable i
s available as a patch for the Sun4,
HP7, and PC platforms on the Xilinx ftp site, ftp.xilinx.com:

PC - ftp://ftp.xilinx.com/pub/swhelp/xact-pc/lca2xnf.zip
SUN4 - ftp://ftp.xilinx.com/pub/swhelp/xact-workstation/lca2xnf.sun4.tar.Z
HPPA - ftp://ftp.xilinx.com/pub/swhelp/xact-workstation/lca2xnf.hppa.tar.Z
