Abstract

The invention discloses a model verification device based on source codes, and the device comprises a source code obtaining module which is used for obtaining target source codes; a first model generation module which is used for modeling the target source codes according to an AADL modeling technology and then generating an AADL model; a second model generation module which is used for convertingthe AADL model into a time automaton model based on a preset conversion mode; and a model checking module which is used for checking the time automaton model by utilizing a preset model detector. Therefore, by adopting the embodiment of the invention, the verification efficiency can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a source code-based model verification device. Background technique [0002] With the rapid development of information technology, the functions of software systems are becoming more and more complex, and the scale is getting bigger and bigger, and the security challenges they face are becoming more and more severe. Especially for safety-critical systems such as aerospace, automotive electronics, industrial control, and military systems, trusted verification of software is particularly important. Formal verification technology is based on formal specification, through in-depth analysis and understanding of the system, to verify whether the system satisfies its given properties, or finds that the system cannot meet the conditions of the properties. [0003] At present, the main formal verification method is theorem proving. Theorem proving mainly uses logical and mathematical ...
