Record #2763

Product Family:  Software

Product Line:  FPGA Implementation

Problem Title:
ngdbuild m1.3: ERROR:basnb:48 - Cannot find or build NGO from
"filename.edn"



Problem Description:
An example of the full error is:

ERROR:basnb:48 - Cannot find or build NGO from
   "N:/xilinx/rene/ipmodulea.edn".
   Please make sure the source file exists and is of a
   legal netlist format (e.g., NGO, EDIF or XNF).

In this case the edif file was generated by Workview
Office 7.31. The  command line used by ngdbuild was:

   ngdbuild -p xc4000e FILENAME.EDN xc4000e.ngd


Solution 1:

Within Windows (95,NT), bring up an MS-DOS Promt:

Type: ngdbuild (or any other executable such as map, par, etc..)

If the executable is not valid and does not bring up the options screen,
the likely cause of the error is incorrect environment variables
on your machine.  Please check to make sure that you have following
valid statements set:

PATH=C:\Xilinx\bin\nt
Xilinx=C:\Xilinx

Typing "path" and/or "set" from the MS-DOS promt should reflect what
you see in the autoexec.bat file in 95 and/or the environment tab from
NT.

Note: If you are using Windows 95, you will need to restart Windows.  If you are

using Windows NT, you may also need to restart Windows.





Solution 2:

Change the command line to either
			    ngdbuild -p xc4000e FILENAME.edn
or
			    ngdbuild -p xc4000e FILENAME

If you are launching ngdbuild from the design manager make sure the input file d
oes not have the .edn in uppercase.



Solution 3:

If you are launching ngdbuild from the design manager make sure
the input file does not have the .edn in uppercase.
