4.1i Project Navigator - "ERROR:Xst - 34test.vf Line 6. parse error, expecting `IDENTIFIER' or `OR" occurs when synthesizing a schematic source file that begins with a numeric character.

Description

Keywords: exit code: 0006, WebPACK, ISE, schematic, IDENTIFIER, XST, Verilog, EXEWRAP

Urgency: Standard

General Description:
When I synthesize an ECS schematic file that begins with a numeric character, Synthesis reports an error. For example, using the XST-Verilog flow to synthesize a schematic named "34test.sch" in Project Navigator causes an error similar to the following:

Compiling source file : 34test.prj
Compiling included source file '34test.vf'
ERROR:Xst - 34test.vf Line 6. parse error, expecting `IDENTIFIER' or `OR'
Continuing compilation of source file '34test.prj'
Compiling included source file 'f:/Xilinx/verilog/src/iSE/unisim_comp.v'
Continuing compilation of source file '34test.prj'
1 error in compilation
-->
EXEWRAP detected a return code of '6' from program 'f:/Xilinx/bin/nt/xst.exe'

Done: failed with exit code: 0006.

NOTE: The error message will be different, depending upon the Synthesis flow used. For more information, please see (Xilinx Answer 12368), (Xilinx Answer 12375), and (Xilinx Answer 12376).

Solution

Project Navigator does not recognize source files with leading numeric characters. To avoid this error, please change the file name so that it begins with an alphabetical character (i.e., "test_34.sch"), and re-synthesize.
