Automatic hardware language transformation system

Abstract

The invention discloses an automatic hardware language transformation system comprising a lexical analysis module, a syntactic analysis and semantic check module, an intermediate representation storage unit and a transformation module. The lexical analysis module is used for transforming a character sequence including keywords, identifiers, constants, character strings, operators and annotations in the Verilog language into tokens. The syntactic analysis and semantic check module is used for realizing syntactic analysis by recognizing structures of expressions, statements, process blocks, modules and the like in a Verilog program according to syntax rules of the Verilog language specified in Bison while performing the semantic check. The intermediate representation storage unit is used for realizing intermediate representation of the different structural bodies of a Verilog source file by the unit of modules. The transformation module is used for transforming the Verilog language into the MSVL (modeling, simulation and verification language) according language transformation rules between the Verilog language and the MSVL.

Description

technical field [0001] The invention relates to the technical field of hardware description language Verilog, in particular to a hardware language automatic conversion system for converting Verilog hardware description programs into equivalent MSVL codes. Background technique [0002] Software simulation is of great significance in hardware design, and it is the main means of logic design, verification and performance analysis. Commonly used commercial simulation products, such as Verilog, are currently the most widely used hardware description language. It is one of the Institute of Electrical and Electronics Engineers (IEEE) standards and is mainly used in digital electronic system design. The language allows designers to use it for various levels of logic design, as well as simulation verification, timing analysis, and logic synthesis for digital logic systems.

Problems solved by technology

[0003] At present, the use of commercial simulation software has become the first choice of IC design engineers, but commercial simulation software is not suitable for general applications such as performance analysis and system evaluation due to limitations such as high cost and complex use environment.
