UML在数字系统设计中的应用

Method of software engineering apply to digital system design

随着EDA（ElectronicDesignAutomation）技术的发展，数字系统的设计的潮流是从抽象级别较高的层次开始，对系统做功能描述，自硕向下地完成整个设计。合理地将软件工程方法和UML运用于数字系统的设计，在系统的分析、建模、系统的设计等方面，将提高数字系统设计的合理性、准确性，提高设计效率，降低开发周期和成本，并能提高系统的生命。

Along with the development in EDA（Electronic Design Automation） technology, digital system design currently start at abstract level, describe the function of system, finish design from top to down. How to use method of software engineering and UML in digital system design with reason, will enhance rationality and veracity, enhance efficiency of design, shorten design cycle and lower cost, and extend life of digital system.
