I has mainly discussed the sofeware and hardware of aribrary waveform generator controlled by the microcontroller in my with the control of the high proformance microcontroller - 80c196kc , this instrument builds up the main circuit adopting single tone and dac of ad9857 . in my project , i . have designed some special circuits with the advanced method of eda ( electron design automation ) based on vhdl and cpld . it can produce standard waveforms such as sine , square , triangle , and generate aribrary waveform according to the user ' s demand , at the same time , it has the ability to produce the amplitude modulation signal based on the carrier of sine and the aribrary waveform 论文中主要对微机控制的任意波形发生器的软硬件设计进行了相应的研究，该任意波形发生器以intel公司16位高性能单片机80c196kc作为控制器，分别利用了ad9857的单音频模式和dac模式组成正弦波和任意波产生的电路，在硬件电路的设计中采用了先进的eda (电子设计自动化)技术，使用vhdl语言和可编程门阵列器件对一些特殊的电路进行了设计。
This master degree thesis , based on the observing of developing actuality of on - site electrical apparatus monitoring technology , aims at overcoming the problems existing in former on - site monitoring system , such as unable to realize multiple channels sampling and hold , unable to carry out multiple channel programmable magnification , unable to monitor frequency , low pick up bits , external rom low speed data saving , inefficient data query method , inflexible debugging and installation , low precision etc . by introducing eda ( electrical design automation ) technology , we put forward a creative circuit design scheme , which can considerable updated the on - site monitor system 本文根据电气设备绝缘在线监测技术的发展现状，针对以往在线监测数据采集系统存在的集成度低，不能实现多通路并行采样，不能实现多通道同时程控放大，不能进行同步频率监测，采样位数较低，采用外部存储器方式，对数据进行查询的访问方式，安装调试不灵活等缺点，提出了应用现代微电子技术电子设计自动化( eda )技术实现对在线监测数据采集系统的改进。
In recent years , the technology of integrate circuit ( ic ) has been developed greatly . methods and tools of the design in integrate circuit ( ic ) have also been developed rapidly . after computer aided design ( cad ) and electronic design automatic ( eda ) were invented , they are used in all of steps of integrate circuit ( ic ) design . and these tools give devisers much help and enhance the efficiency of the design . but the size of integrate circuit ( ic ) chip was enlarged greately and the structure of integrate circuit ( ic ) chip became more and more complex 随着集成电路和微电子技术的发展,集成电路设计的设计手段和设计工具也取得了很大发展,特别是计算机辅助设计( cad )和电子设计自动化( eda )工具。它们应用于集成电路设计的各个环节,这给设计人员带了很大的帮助,极大的提高了设计效率。但是,集成电路芯片的规模日益增大,结构越来越复杂,计算机辅助设计和电子设计自动化软件工具也显得越来越力不从心。
The design complexity and system function of electronic system have been increasing largely , the competition from the global also shorten the design period , therefore , the demand for the tools of electronic design automatic is tremendous and the requirement for efficiency of eda tools is more and more precise 电子系统的设计复杂性和系统功能一直在呈几何级数增长，全球的竞争又加剧了产品开发周期的缩短。因此，对电子设计自动化工具的需求越来越迫切，要求也日益提高，这一切促进了eda的发展，加速了设计方法和设计工具的更新换代。
