摘要
异步串行通信是广泛使用的通信方式。由于大规模FPGA/CPLD的出现和EDA技术的发展,使得自己设计元器件成为可能,且存在设计周期短、成本低、设计灵活的优点。在Multisim 10软件平台上使用VHDL语言设计异步串行通信电路,并用Multisim建立该电路的模型。仿真实验的结果验证了异步串行通信电路的通信协议、帧格式、波形特性、误码校验以及Multisim的仿真步骤。
Asynchronous serial communications is widely used in all the kinds of electronic circuit.It＇s possible for us to design components because the appearance of large scale FPGA/CPLD and the development of EDA technology.It also has such advantages as short cycle,low cost and design flexibility.On the platform of Multisim 10,we use VHDL to design an asynchronous serial circle and build its simulation model.The simulation results have verified the communication protocol,frame format,wave＇s characteristics,validation of BER,and simulation steps for multisim in the asynchronous serial circle.
