11.2/11.3/11.4 XST - "ERROR:Xst:2996 - XST patch Expired"
Description
When I use the CORE Generator tool to generate a new core or regenerate an existing core, errors similar to the following occur:
"ERROR:coreutil - Exception caught when running XST synthesis!
ERROR:coreutil - Failure to generate output products
ERROR:coreutil:576 - An error occurred while running Java. Please examine the console or coregen log file for a specific IP related error.
For more information please search the Xilinx Answers Database for this error: http://www.xilinx.com/support
ERROR:coreutil - XST has returned an error: ERROR:Xst:2996 - XST patch Expired."
How can I resolve it?
Solution
An XST file that is distributed with ISE 11.2/11.3 and 11.4 software for use with the CORE Generator tool expired on December 15, 2009.
When CORE Generator calls XST in the background to generate the core, XST exits because a time-stamp in the file has inadvertently expired.
Following is the current known list of cores that are affected by this issue:
- DDS Compiler - dds_compiler_v4_0 (11.3)
- Complex Multiplier - cmpy_v3_1 (11.4)
- Fast Fourier Transform - xfft_v7_0 (11.4)
- Divider Generator - div_gen_v3_0 (11.2)
- Reed-Solomon Decoder - rs_decoder_v7_0 (11.2)
- Reed-Solomon Encoder - rs_encoder_v7_0 (11.2)
To fix this issue, complete the following steps:
- Download the ZIP file from:
http://www.xilinx.com/txpatches/pub/applications/dsp/ar33993_11.x_lin_win.zip - Unzip the file to the $XILINX area.
Example : c:\xilinx\11.1\ise - The "ipset.txt" file will be overwritten by the unzip.
To test this patch, run the CORE Generator tool again; the core should generate without any errors.
