ChipScope - Inserter - When I implement a design including a CDC file, I see "java.io.IOException: Cannot run program "coregen".."


When you run implementation on a design that contains a CDC file generation of the ChipScope tool, the cores error out with the following:

Generating cores using CORE Generator. Please be patient as this can take several minutes...
Generating core 1 of 2 icon_pro.ngc...
java.io.IOException: Cannot run program "coregen" (in directory "..."): java.io.IOException: error=12, Cannot allocate memory

This will occur when you have another Java based tool open such as Modelsim or PlanAhead. The issue is related to the amount of contiguous memory available to java on your system. There are two possible workarounds:
1 - Close the other tool. This will deallocate memory and likely cause the CORE Generator/inserter java process to complete
2 - Switch to a 64-bit system
