Generating a transition system for use with model checking

摘要

The invention concerns model program analysis of software code using model checking. Initially, a transition system (22) and an extensible markup language (XML) (24) representation of the data is generated. Next, labels (26) for the transition system are generated by querying the XML representation of the data using (markup) query language. The labels and the structure of the transition system are then used as input to model checking techniques to analyse the software code (28). It is an advantage of the invention that the problem of labelling a transition system can be transformed into the XML domain so that detailed information about the software code can be extracted using queries in a format that can be run in the XML domain which are well known. At the same time the transformation to the XML domain does not prevent the use of efficient model checking technologies.

1. A non-transitory machine-readable medium storing one or more instructions for generating a labeled transition system for use with model checking of source code in a computer, which when executed by a processor of the computer, cause the processor to perform operations comprising:
generating a transition system from the source code; generating an extensible markup language (XML) representation of the source code comprised of nodes, each node having an identifier; generating labels for the transition system to form the labeled transition system by running a query on the XML representation of the source code using query language to return an identifier of a node that matches the query and labeling a node in the transition system identified by the same identifier as the node that matched the query; and using the labels and the structure of the labeled transition system as input to model checking techniques to analyze the source code.
