Problems solved by technology

These patents are all based on the current relatively mature hardware modeling theory. The disadvantage of these systems is that they only verify the relatively simple state of the hardware and cannot handle the analysis and optimization of concurrent and real-time programs.
From the above discussion, it can be seen that the current concurrent real-time program verification and optimization patents are mainly focused on hardware, and there is no good treatment method for state explosion, nor does it involve program optimization related to embedded concurrent real-time software

Abstract

The invention provides a concurrent real-time program verification optimized processing system and method based on rewrite logic and belongs to the technical field of computer application. The system comprises a program model module, a property model module and a rewrite logic verification module. The method comprises the following steps: verifying a concurrent real-time program by virtue of rewrite logic; carrying out status space optimization on the property to be verified and model of the system by virtue of an algebraic model; adopting a time meta model to process real-time related property; and using equivalent state compression and algebraic simulation optimization so as to improve the program verification efficiency.

Description

technical field [0001] The present invention relates to a system and method in the field of computer application technology, in particular to an optimized processing system and method for concurrent real-time program verification based on rewriting logic. Background technique [0002] According to the general framework of formal methods, it is first necessary to obtain the formal model M (Model, or Specification) of the system, and then establish the correctness, liveness and other judgment properties of the system (Property). Because the traditional system development method cannot cope with the increasingly complex and high reliability requirements of the system. For example, embedded software has relatively high requirements on real-time, and is relatively strict on system performance and size (footprint). Especially in the key application fields, the reliability and robustness of the system are required to be higher. In the aviation field, the system is even required ...
