基于EDA技术的继电控制回路设计

指出了机电设备常见电气继电控制在使用中的不足，阐述了在继电控制回路的开发设计中运用EDA技术的可行性，介绍了用VHDL语言设计单片控制系统的方法，给出了电机周期性正反转运行的VHDL设计程序和仿真波形图．仿真结果证明了这种设计方法的正确性．这种设计理念对传统电气继电控制的设计是一种挑战．

Design of Relay-controlled Circuit Based on EDA Technology

The shortcomings in application for ordinary electric relay controlled circuits in electrical - mechanical equipment were pointed out, and the feasibility for applying EDA to develop and design relay - controlled circuit was expounded, also, the approach to design single - chip system by using VHDL was recommended. The VHDL program and simulating waveform for motor running forward & reversely periodically were introduced.The validity was proven by the simulating results.This ideology is a challenge to traitional design approach for relay- controlled circuit.
