Error: Error writing sopcinfo report java.lang.OutOfMemoryError: Java heap space

Description

You may see the following or similar error when generating a large design from Qsys.

Error: Error writing sopcinfo report java.lang.OutOfMemoryError: Java heap space

Resolution

To work around the problem, launch Qsys from a command prompt using the qsys-edit command with the --jvm-max-heap-size=<size><unit> command line argument, where <size> is an integer value and <unit> is m (or M) for megabytes or g (or G) for gigabytes. This will run Qsys with an increased Java heap size. The qsys-edit command should be run from the current Quartus project directory.

For example, to run qsys with increased heap from the Windows command prompt:

1. cd <quartus_project_directory>
2. %QUARTUS_ROOTDIR%\sopc_builder\bin\qsys-edit --jvm-max-heap-size=<size><unit>

For example, to run qsys with increased heap from the Linux command prompt:

1. cd <quartus_project_directory>
2. /sopc_builder/bin/qsys-edit --jvm-max-heap-size=<size><unit>

The Qsys default java heap size is 512M. Specifying a larger value will avoid running out of heap memory.

For more information regarding qsys-edit command line arguments, please see the Running the Qsys Editor with qsys-edit (PDF) document.

This problem is addressed and resolved in the 14.0 release of the Quartus II software.
