EDA technology open innovation platform based on research and design
Abstract: with the progress of electronic technology and computer technology, involved in the content of communication, national defense, aerospace, industrial automation, instrumentation and other fields of electronic system design of EDA technology are rising at an alarming rate, it has was the of the frontiers of modern electronic technology development. Is introduced in this paper stepper motor development board based on EDA technology design and both keyboard, dial code switch, led, LCD step, automatically complete logic compiler, simplifying the logic, logical partitioning, logic synthesis and logic optimization and simulation test until established electronic circuit system function realization. Design the useful equipment of a system, the key circuit of the system with one or a few slices of application specific integrated circuit (ASIC), and then using hardware description system to realize a design of a system level device, the integrated and adapters to generate the final target device, this kind of design method called electronic design method of high level.
Keywords: Keyboard, Dial switch, LED, LCD, Stepper motor

基于EDA技术的开放式创新平台研究与设计 引言
伴随越来越多的现在复杂科技电子系统的进展, 单单依靠人力手动电子技术已经难以达到人们的需求，所以只能发展更高更急速的技术来满足人们所需要EDA技术工具。
电子设计自动化我们将其称之为EDA，要依靠电脑来完成所需要的技术,然而在EDA技术的范畴中, 依靠硬件描述语言HDL来设置指定的文件,能够不通过人为的设计出逻辑编译, 还原,分离,总体及化简,布置及模拟, 直到出现一个必要的编辑器试配器心片印射及加载一系列的制作,最后得到得电子科技系统。
