EDA技术是用于电子产品设计中比较先进的技术,可以代替设计者完成电子系统设计中的大部分工作,而且可以直接从程序中修改错误及系统功能而不需要硬件电路的支持,既缩短了研发周期,又大大节约了成本,受到了电子工程师的青睐。在设计中采用EDA技术,通过广泛应用的VHDL硬件电路描述语言,实现交通灯系统控制器的设计,利用MAXPLUSⅡ集成开发环境进行综合、仿真,并下载到CPLD可编程逻辑器件中,完成系统的控制任务。
EDA technology is used in electronic product design more advanced technology that can replace the designer to do most of the work in the electronic system design, and can directly modify the error and system functions from the program without the support of the hardware circuit, both shortened R & D cycle, but also greatly reduce costs, by electronic engineers of all ages. In the design using EDA technology, through the widely used VHDL hardware circuit description language, to achieve the design of traffic light system controller, using MAXPLUS Ⅱ integrated development environment for synthesis, simulation, and downloaded to the CPLD programmable logic device to complete the system control task.
