AR# 6897

説明

I have created a schematic using XC4000 non-E UNIFIED libraries with pre-A1.5 Xilinx design tools. I am able to open the schematic in pld_da, but I am unable to run "Check Design", nor am I able to run Convert Design, to convert my design to a newer Xilinx technology such as the XC4000E, or XC4000X family. When running "Check Design", I receive messages similar to the following: 

// Error: Could not determine current version of and2/part for instance I$1 

// Error: Could not determine current version of bufg/part for instance I$2 

// Error: Could not determine current version of cb2ce/part for instance I$3 

When running "Convert Design", I receive messages similar to the following in the transcript window: 

// Error: Library -->$LCA/xc4000/ does not exist . (from: Uims/base_toolkit/ui_session_tk 01  

OR in the pld_da window I see: 

Error: Library -->$LCA/xc4000/ does not exist

ソリューション

This is due to the fact that in the A1.5 and later software the XC4000 library was removed due to library install size reasons. Also since the silicon is no longer available, the library was removed to deter any NEW designs into the XC4000 (non-E) devices. 

To run Convert Design, you must have the XC4000 library in the $LCA ($XILINX/mentor/data) area. This library can be downloaded from the Xilinx ftp site: 

http://www.xilinx.com/txpatches/pub/swhelp/mentor/xc4000.tar.Z
 

You must have write privileges into the $LCA directory to copy these library files. 

For more information on running Convert Design, please see (Xilinx Answer 798).
