基于Multisim11.0和VHDL的电子电路仿真方法

Multisim11.0 and VHDL-based Simulation of Electronic Circuits

针对当前复杂电子电路故障数据获取难,仿真软件扩展难度大、灵活性较差的问题,通过深入研究NI公司的Multi-sim11.0软件和VHDL硬件描述语言,讨论了采用Multisim11.0与VHDL相结合的电子电路仿真的新途径,通过对可编程并行接口芯片8255A的模块仿真与功能验证,证明了此种方法的有效性。

Today,it is difficult to acquire fault data in complex electronic circuit and simulation software is difficult to extend.Through studying the NI company＇s Multisim11.0 software and VHDL hardware description language,the new way of electronic circuit simulation with the combination of VHDL and Multisim11.0 is discussed.Through the 8255A programmable parallel interface chip module simulation and functional verification,the effectiveness of this method has been proved.
