You need either a Java Runtime Environment or a Java Development Kit installed. 

Depending on your platform, you have to make sure the JAVA_HOME environment variable points to the directory where the version was installed (in some platforms the installer takes care of this for you), and that you have $JAVA_HOME/bin in your PATH.

Memory and Time Requirements

When KLA executes a local analysis, it starts a JVM for every analysis step.

By default:

  • JVM is configured to take a maximum of 1GB per concurrent analysis

  • Max time (timeout) for every analysis step is configured to 60 minutes.

These default values are usually valid for most of the analyses


For analyses that contain more than 5,000 sources files and/or more than 1.5 Million lines of code , it's recommended to increase those values..
