[0039] Compiler Architecture Design

[0040]For its architecture design, considering that for different application occasions, the final object codes that users care about are quite different, if the entire compiler is developed according to user needs, the versatility of the compiler will be reduced. In order to solve the universal problem, the present invention proposes and designs a layered architecture design of a general compiler, such as figure 1 shown. This module is divided into two parts: compiled application support module (bottom module) and compiled application module (upper module). Modules are called through API (Application Programming Interface) and communicate based on custom messages. The compiling application support module is based on the latest Gerber file format specification and uses regular expressions as a tool to realize lexical analysis, syntax analysis, information matching and intermediate code generation of Gerber files. This module encapsulates...

Abstract

The invention discloses a Gerber file compiler based on regular expressions, and relates to the technical field of high-level language compilation or explanation. The Gerber file compiler comprises an architecture part and an algorithm implementation part, wherein the architecture part comprises a compilation application module and a compilation application support module, and call between the compilation application module and the compilation application support module is achieved through an API; according to algorithm implementation, a Gerber file is described in a formalized mode through three-type grammar, then the regular expressions are used for building corresponding rule lists for lexical analysis and grammatical analysis, according to the rule lists, lexical analysis and grammatical analysis threads are executed in a compiling mode, image information matching is performed at the same time, and matching results are stored through two-way linked lists. The compiler is used for compiling the Gerber file and has the advantages of being high in generality and compiling efficiency.

Description

technical field [0001] The invention relates to the technical field of editing or explaining high-level languages, in particular to a Gerber file compiler based on regular expressions. Background technique [0002] The Gerber file format was first proposed by the Gerber Company of the United States and used in the company's own optical plotter, and was later acquired by Ucamco. Now the specification of the Gerber file format is formulated by Ucamco, and the latest version was released in February 2014. Gerber files are a collection of document formats for PCB industry software to describe circuit board (circuit layer, solder mask layer, character layer, etc.) images and processing data such as drilling and milling. In the actual production process, in order to protect the independent intellectual property rights of the circuit board design, the user or the enterprise design department often only provides the Gerber file of the circuit board to the PCB manufacturing departmen...
