Special care was (and is) taken to provide strong proof support for all validation and verification tasks. KIV can handle large scale formal models by efficient proof techniques and an ergonomical user interface. It has been used in a number of industrial pilot applications, but is also useful as an educational tool for formal methods courses.

KIV uses the Scala programming language and is integrated into the Eclipse platform as a plugin.

KIV comes as an Eclipse plugin which you can download from the update site listed below.

Installation steps

1. Download and install the Eclipse IDE for Java Developers via the Eclipse download site ( https://www.eclipse.org/downloads/packages/release/2022-03/r). Currently, it is recommended to use version 2022-03 (4.23), newer versions could occasionally cause problems. In case you run into problems with version 2022-03 (4.23) as well, the Oxygen version can still be used ( https://www.eclipse.org/downloads/packages/release/oxygen/3a).
2. In Eclipse, select Help → Install New Software ....
3. Add the update site for KIV for Eclipse  https://kiv.isse.de/releases/v10/stable/site and install the features KIV Eclipse Integration and KIV Standard Library as well as all necessary KIV Dependencies.
4. After restarting Eclipse, you can open the KIV perspective under Window then Open Perspective → Other.
5. You may wish to read the Quick Start.

Requirements

• Java 1.8 or greater
• Eclipse Oxygen or newer (the plugin is developed with ScalaIDE, which is based on Eclipse Oxygen, so other Eclipse versions are currently not tested exhaustively)
