Additionally, the following URLs should also be accessible to contact Kiuwan support:

Java

[currently recommended from 8 to 11]

You need either a Java Runtime Environment (JRE) or a Java Development Kit (JDK) installed. 

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

Windows Configuration for JAVA_HOME

Windows 8 and higher:

  1. In Search, search for and then select: System (Control Panel)
  2. Click the Advanced system settings link.
  3. Click Environment Variables. In the section System Variables, find the PATH environment variable and select it. Click Edit. If the PATH environment variable does not exist, click New.
  4. In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. Click OK. Close all remaining windows by clicking OK.
  5. Reopen Command prompt window, and run your Java code.

For other operating systems please see the Java Help page. 

Memory and Time Requirements

When KLA executes a local analysis, it starts a Java Virtual Machine (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 sufficient for most analyses

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