Readme File for using the compile_nc_vhdl.pl script
Date : 21 February, 2003
------------------------------------------------------------------------

1. The script compile_nc_vhdl_51.pl analyzes the Xilinx libraries for use
in simulations with NC-VHDL.


2. How to run "compile_nc_vhdl.pl" - UNIX/LINUX

First make sure that the following environment variables are set up 
in the shell environment. Examples of how to do this in the C-shell 
are given below.

Note : $XILINX - environment variable points to the path where the Xilinx 
  installation exists

setenv XILINX /net/indstore2/vol/vol0/sld/rnd/sk/Xilinx/ISE4.1i/xilinx
set path = (. $XILINX/cadence/bin $XILINX/bin/sol  $path)
setenv LD_LIBRARY_PATH $XILINX/bin/sol:${LD_LIBRARY_PATH}

Make sure that your environment is correctly set up so that NCVHDL can
execute correctly in this environment.

To invoke the script, use the following : 

%perl compile_nc_vhdl_51.pl <Library> [Output Directory]
<Library> : Library name which you would like to analyze, one at a time. 
   Library can be simprim or unisim or xilinxcorelib.
   Alternatively, use "all" to analyze all the libraries in one shot.
[Output Directory] : Specify the destination directory where Xilinx 
   models would be analyzed (and stored).
   Note: Relative paths are not currently supported.  Pleas specify the
         full implicit path to the output directory.

3. How to run "compile_nc_vhdl.pl" - Windows

First make sure that the XILINX environment variable is set up
in the command shell. An example is given below.

Note : The XILINX environment variable points to the path where the 
Xilinx installation exists

set XILINX=g:\xilinx

Make sure that your environment is correctly set up so that NCVHDL can
execute correctly in this environment.

To invoke the script, use the following :

%perl compile_nc_vhdl_51.pl <Library> [Output Directory]
<Library> : Library name which you would like to analyze, one at a time.
   Library can be logiblox or simprim or unisim or xilinxcorelib.
   Alternatively, use "all" to analyze all the libraries in one shot.
[Output Directory] : Specify the destination directory where Xilinx
   models would be analyzed (and stored).

4. Once the script completes execution, the compile_nc_vhdl.pl script 
will print the Library definitions to the screen. Example :

DEFINE simprim /tmp/milinx/vhdl/ncvhdl/simprims
DEFINE unisim /tmp/milinx/vhdl/ncvhdl/unisims
DEFINE xilinxcorelib /tmp/milinx/vhdl/ncvhdl/XilinxCoreLib

The cds.lib file of your project work directory needs to be appended 
with the relevant library definitions printed by the script. After this 
is done, your project VHDL files can be analyzed and simulated by NCVHDL.

5. The compile_nc_vhdl_51.pl is an example script and users are free to 
   modify/copy according to their need.
