摘要
基于EDA技术,使用FPGA芯片和VHDL语言,设计了一种PS/2设备接口电路。介绍了硬件连接、通信协议、设计过程及仿真结果。采用自顶向下的设计思路,充分发挥EDA技术的优势,大大缩短了设计周期。软件仿真及硬件调试表明,设计中的各个模块之间能够正确地传送数据,性能稳定,达到了预期目标。
A PS/2 interface circuit is designed based on FPGA chip and VHDL language. Hardware connection, communication protocol, design process and simulation result are introduced. Using the top-down design ideas, giving full play to the advantage of EDA technology, the design greatly shortens the design cycle. Software simulation and hardware debugging demonstrate that data can be transmitted accurately between the modules in the design and the system runs normally.
