متن کاملAn Approach to Model Checking Ada Programs
This paper describes a tool-supported method for the formal verification of Ada programs. It presents ATOS, a tool that automatically extracts a model in SPIN from an Ada Program, together with a set of properties that state the correctness of the model. ATOS is also capable of extracting properties from user-provided annotations in Ada programs, inspired by the Spark Annotation language. The g...
