Arcade

Arcade is a framework for the verification of programs for programmable logic controllers. Its development started in 2011 as a reincarnation of the [mc]square framework, tailored for the support of PLC semantics and specific features.

The expressed aim of Arcade is to aid PLC developers in finding bugs and verifying functional (safety) properties without requiring deep knowledge of formal methods. This is provided by offering direct support of different PLC programming languages and easy access to different analysis functions.

Features

Arcade consists of a static analysis engine for PLC languages.
