介紹一種應(yīng)用于數(shù)字系統(tǒng)設(shè)計(jì)中的基于函數(shù)式語(yǔ)言的代碼解析方案，主要包括該函數(shù)式語(yǔ)言和解析工具的介紹，該語(yǔ)言的詞法與語(yǔ)法分析程序的結(jié)構(gòu)介紹，由語(yǔ)法樹(shù)到語(yǔ)法規(guī)則到抽象語(yǔ)法樹(shù)的生成過(guò)程，以及具體的應(yīng)用實(shí)例。該解析方案已經(jīng)成功應(yīng)用于數(shù)字系統(tǒng)的設(shè)計(jì)中。

Abstract: Introduce a method for parsing, which is based on functional language and used in digital system design, including the introduction of the functional language and the parsing tools, the structure of lexical analysis and syntax analysis, the design of syntax tree, the definition of syntax rules, the structure and the generation of abstract syntax tree, and an example to indicate the output result of this method. This method has been successfully used in digital system design project.
Key words: Lexical analysis; Syntax analysis; Parse; Abstract Syntax Tree
