【摘要】 对包含微控制器核心的系统进行模拟是ASIC以及系统设计中的重要问题。利用VHDL语言对微处理器进行行为级的描述,可以大幅度提高CAD模拟软件中微控制器系统的模拟速度。本文讨论了包含微控制器核心的系统的特点,介绍了采用VHDL微控制器仿真模型的系统模拟方法以及相应VHDL微控制器仿真模型的设计方法,并以8位微控制器MCS51为例,分析了VHDL微控制器仿真模型的结构和特点,最后介绍了一个模拟应用实例。更多还原

【Abstract】 The simulation of systems with a microcontroller core is important to ASIC and sys-tem design. By using a behavioral VHDL model of microcontroller, we can improve the speed of simulation efficiently due to the characteristic of these systems. In this paper, the method of sys-tem simulation and a behavioral VHDL model of microcontroller for simulation is discussed. Fur-thermore , VHDL model for a 8-bit microcontroller MCS51 and its application are introduced as an example.更多还原
