LogiCORE Virtex-4 Aurora v2.4 - An error message occurs in COREGen when generating Aurora v2.4 after installing 8.2 IP Update #2


After installing 8.2 IP#2_1 (ise_82i_ip_update2_1.zip), the following error message occurs when running Aurora v2.4:

"ERROR:coreutil - Portability:77 - Port_Compress::Read() : The buffer size is too small

32768, needed 33855).

ERROR:coreutil - Failure to generate output products

ERROR:coreutil - An error occurred while running Java. Please examine the console or coregen log file for a specific IP related error.

If there is no specific error the problem may be due to memory limitations. For more information please consult solution record 21955 available from:

Finished Generating.

ERROR:sim:57 - Error found during generation."


This failure results from a problem with the IP#2_1 build. Xilinx has fixed this issue and re-released 8.2.03 IP#2 on the Download Center page.

The corrected version of the IP installer is named "ise_82i_ip_update2_3.zip." You can obtain this fixed IP Update from the Download Center at:
