** OBSOLETE ** V1.5, V1.4 COREGEN, VIEWLOGIC: Error: Could not read symbol file <path_to_SYM_dir>\SYM\<modulename>.1 java.io.File NotFoundException: <path_to_SYM_dir>\SYM\<modulename>.1

Description

Keywords: Core Generator, coregen, Viewlogic, java.io.File,
Viewsym

Urgency: Standard

Problem Description:

When generating a module using the Xilinx CORE Generator for a
Viewlogic schematic design, you may get the following error:

Error: Could not read symbol file
c:\dsp_proj\regsub2\SYM\regsub2.1
java.io.FileNotFoundException:
c:\dsp_proj\regsub2\SYM\regsub2.1
Error: Generating Viewsym
Error: Errors Occurred during during the generation of regsub2
Error: Could not read symbol file
c:\dsp_proj\regsub2\SYM\regsub2.1
java.io.FileNotFoundException:
c:\dsp_proj\regsub2\SYM\regsub2.1
Error: Generating Viewsym
Error: Errors Occurred during during the generation of regsub2

This error messge indicates that COREGEN had a problem
generating the symbol for the Core Generator module.

Solution


In COREGEN, the Viewlogic symbol generation process involves
several programs external to the native COREGEN application.
These are called by a batch file on Windows95 and NT called VLLINK.BAT,
and a script file called "vllink" (on UNIX). These programs
call a Viewlogic utility call VHDL2SYM.EXE (vhdl2sym), which
takes a VHDL port list as input, and generates a symbol from
it.

The "Could not read symbol" error indicates that something has
gone wrong during the symbol generation process.

Before generating the Coregen module, be sure you have
set the path and alias correctly for your design directory
in the Workview Office Project Manager. The alias for the
directory in which you generate the Core should be "coregen"
or "primary".

Be sure to check that the spelling of the alias, "coregen", is
correct, and that it matches the setting for "Symbol Library"
in the Core Generator under the

Options ->System Options

After saving the Project Manager with the correct library
setting, re-run COREGEN.

Viewlogic Schematic Flow, see
