9.1i CORE Generator - Licensed IP Cores cannot be generated on Windows XP64


Keywords: license, IP, core, customize, java, flexlm, exception

Generating a licensed IP core on Windows XP64 results in the following warning:

"WARNING:coreutil:202 - No FLEXlm support on current platform.
An unexpected error has been detected by HotSpot Virtual Machine
EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000005a731ec, pid=2680, tid=341
Java VM: Java HotSpot(TM) 64-Bit Server VM (1.5.0_04-b05 interpreted mode # Problematic frame
C [libCoreu_Interface.dll+0x31ec
An error report file with more information is saved as hs_err_pid2680.log"


A user can determine if an IP Core is JAVA-based by looking at the Generate/Finish button in the core's customization GUI. If there is a Generate button, the IP Core GUI is JAVA-based. If there is a Finish button, the IP Core GUI is C++-based. All new IP cores will be created in C++.

To work around this issue, use a platform other than Windows XP64 if a JAVA-based IP core must be generated.

This issue has been fixed in the latest Service Pack for ISE.
The first Service Pack containing this fix is SP2 for ISE 9.1i.
