Abstract

A semantic consistency verification method for software design and implementation comprises the following steps: carrying out formalized modeling on the basis of a design document, and reorganizing information in the design document into a demand model meeting formalized verification requirements through a formalized modeling language; performing formalized modeling on the basis of engineering realization, and reorganizing information in the engineering code into a realization model meeting formalized verification requirements through a formalized modeling language; and performing formalized semantic consistency verification on the demand model and the implementation model, and judging the consistency of software design and implementation according to a consistency verification result. Bymeans of the method that formal modeling is conducted on a design document and engineering codes respectively, and then refined inspection is conducted, a means for verifying the consistency between software design and implementation is provided. And a powerful available tool is provided for testers to confirm the software security by taking strict demonstration in mathematics as a guarantee.

Description

technical field [0001] The invention relates to the technical field of equivalence verification of software algorithm models and code implementations, in particular to a method for formally modeling software design using formal modeling tools and verifying semantic equivalence between algorithm models and code implementations. Background technique [0002] In the field of engineering, there is a type of embedded software that has extremely strict requirements on safety, such as the control subsystem of a large and complex mechanical system. Once an error occurs, it will often cause equipment damage and casualties. This type of software is usually called safety-critical embedded software, and its safety and reliability are related to the success or failure of the entire system task. [0003] At present, the testing of safety-critical embedded software is usually verified by manual review and dynamic testing. Due to the variety of control systems, different use environments o...
