数字系统的现代软件设计

数字系统设计目前有传统的设计方法和现代软件的设计方法.传统硬件设计方法是自底向上的设计,只有在电路搭建的后期才能进行仿真,发现问题迟,文档资料量大、不易阅读,浪费人力物力.现代软件设计是自顶向下逐步细化的模块化设计,可降低设计难度,在设计的每一步都可进行仿真,能及早发现问题,缩短开发周期,且文件资料归档方便,可节省大量的人力物力资源,提高产品的研发效益.

Modern Software Designing of Digital System

Traditional digital hardware system was designed from bottom to top. Its main unit was made up of general logic components. The simulation and debugging of system were processed in the late stage of the hardware design. The circuit schematic was used as the main file of the design. The development of the digital system was therefore limited. The modern software of system was designed from top to bottom. The designing miniaturization and volume rationalization of the system was realized. The source file of the HDL was obtained. The design can effectively shorten the development cycle,reduce design cost and improve the research and development benefit.
