AR# 33524 11.x ChipScope Pro - IBERT - CORE Generator interface crashes when I hit generate for my Virtex-6/Spartan-6 FPGA IBERT core
Description
When I select generate in the CORE Generator interface while generating my IBERT core for Virtex-6 GTX FPGA or Spartan-6 GTP FPGA, the interface closes and the core is not generated. How do I work around this issue?
OR
When I import an existing XCO file to generate my IBERT core for Virtex-6 GTX FPGA or Spartan-6 GTP FPGA and hit generate, implementation runs for a while and then the interface crashes or I see the error below. How do I work around this issue?
CORE Generator Error
Solution
XCO import crash
Importing an XCO using the menu option causes a crash. To load an existing XCO file for re-customization/generation, copy it to the same directory that contains the project CGP file, open the CORE Generator tool, then re-customize the core by selecting it in the lower-left corner.
Alternatively, if this does not help, you can set the following environment variable
set JAVA_TOOL_OPTIONS="-Xss16m"
For instructions on how to set an environment variable see (Xilinx Answer 11630).
GUI Selection Crash
This will happen if you have not selected a valid GT site. The interface will crash without any warning. Rerun core generation, and on the "Select GTX/P and Reference Clock for Line Rate x" page ensure you have selected a valid GT location.
This issue will be resolved in ChipScope Pro Analyzer 11.4.
