本课程设计的基本任务

本课程设计的基本任务，是着重提高学生在数字集成电路应用方面的实践技能，基本了解数字系统设计的一般方法。树立严肃认真、一丝不苟、实事求是的科学作风，并培养学生具有一定的生产观点、经济观点、全面观点及团结协作的精神。培养学生综合运用理论知识分析和解决实际问题的能力。学生通过电路设计、安装、调试、整理资料等环节，初步掌握工程设计方法和组织实践的基本技能，逐步熟悉开展科学实践的程序和方法。

§1 进行数字课程设计的一般步骤

1.分析确定任务

确定应用系统的功能指标和技术参数，这是系统设计的起点和依据，它将贯穿于系统设计的全过程，必须认真做好这个工作，在确定

任务的阶段中必须明确。

1.本应用系统需要达到的主要目标是什么，有多少个回路，有几

个参数需要进行检测和控制？检测和控制的精度为多少？

2.本应用系统有多少输入信号和输出信号？输入信号的形式和电

压等级及变化频率情况，输出信号的形式，电压等级和驱动功

率有何要求？

3.本应用系统的工作环境情况如：温度、湿度、供电质量、电磁

干扰等，是否需要采用特殊的安全保护和抗干扰措施。

4.本应用系统的经济指标，特别是对新产品的开发，应当综合考

虑成本，可靠性，可维护性以及经济效益和社会效益，参考国

内外同类产品的资料，提出比较合理的技术指标，使所开发的

产品具有最佳的性能价格比。

2.理论设计（自顶而下）

1.认真分析设计任务，通过调查研究，查阅资料来初定系统结构

的总体方案；

2.进行总体功能设计，划分功能模块，画出总体设计框图，注明

各单元电路间接口信号，并画出一些重要控制信号的时序图；

3.按照设计要求，具体分析每个模块的逻辑，选用合适的器件和
