Workshop on Software Correctness and Reliability

All information on the workshop 2014 can be found here.

The slides and videos of 2013 are available on the workshop website

Chalice is a language and program verifier that detects bugs in concurrent programs. The Chalice language is a small, class-based language that supports concurrency via threads, monitors, and messages. Developers can make the implicit assumptions about their code explicit via contracts. The Chalice program verifier checks that the given contracts are never violated and detects other errors such as data races and deadlocks. Chalice is implemented in Scala, on top of the Boogie verification engine and the automatic theorem prover Z3.

Key Results

Chalice is available as part of the Boogie open source release. The Chalice tutorial presents Chalice from a programmer’s perspective, whereas our ESOP 2009 paper explains the details of Chalice’s verification methodology.


Chalice is a collaboration with Rustan Leino, Microsoft Research, and Jan Smans, Katholieke Universiteit Leuven.
