Abstract

The invention belongs to the technical field of computer programming languages and application, and discloses an explanation system and method for Python programming language XD-M which comprises the following steps: for basic statements in an XD-M language and statements from a modeling simulation verification language MSVL, carrying out interpretation by a method of calling a bottom layer interface of an MSVL interpreter; for statements with XD-M language characteristics, creating an equivalent MSVL syntax tree for the statements, expanding an underlying interface, and writting an interpretation method for the statements by an underlying layer. An XD-M program written by using the XD-M language can be subjected to modeling, simulation and verification, so that the correctness, reliability and safety of the XD-M language are improved, a Python-like simple variable is used without a programming style of type declaration, and the flexibility of the XD-M program is improved; the invention depends on a MinGW development environment.

Description

technical field [0001] The invention belongs to the field of computer programming language and application technology, and in particular relates to an interpretation system and method of a Python-like programming language XD-M. Background technique [0002] At present, the scale of software and hardware systems is getting larger and larger. Due to the lack of relevant design and requirements documents for some large software and hardware systems, it is becoming more and more difficult to understand and maintain these systems. Some updates and troubleshooting operations are likely to bring potential loopholes , and cause serious security problems. Formal methods are often used to improve the correctness, reliability and security of hardware and software systems. [0003] Formal verification is based on mathematical methods to standardize and verify computer software and hardware systems. It has the characteristics of strictness and completeness, and has received extensive at...
