ARC is the AltaRica Checker. Its main purpose is to offer model-checking algorithms to verify if an AltaRica model satisfies critical properties. Requirements are described as fixpoint equations or CTL* formulas. For the model-checking part, this tool is essentially an integration of functionalities of two older tools Acheck and MEC 5.
ARC is a command-line oriented tool that offers, beside model-cheking, many other kind of commands to analyse or translate AltaRica models. Main features implemented in ARC are listed below:
- Support of the AltaRica language with extension proposed during ACI Persee
- support for compound types (arrays, structures)
- definition of abstract types and signatures of functions
- Acheck specifications are supported using explicit or symbolic representation (however not all the set of commands are supported in both encoding)
- MEC 5 specifications with Decision Diagrams encoding. ARC extends the set of predefined sets with, for instance,
N!reachthat specifies the set of reachable configurations of the node N.
- ARC integrates an small graphical tool called AltaRica Studio.
- Large relations can be serialized in binary files for future use.
- Preprocessors can be specified using the configuration file of ARC
- CTL* logic is supported in Acheck specs or can be checked separately.
