SOPC实验--自定义PWM组件:以带一个Avalon Slave 接口的PWM 组件为例，说明如何自定义组件。，一个Avalon Slave 接口可以有clk、chipselect、address、read、readdata、write 及writedata 等信号，但这些信号都不是必需的。
一、功能
我们要实现的PWM 组件具有以下功能：
1． PWM 的周期可改，用period 寄存器存储；
2． PWM 的占空比可改，用duty 寄存器存储。
二、Avalon Slave 接口信号的设计
1．Clk：为PWM 提供时钟；
2．Write：写信号，可以通过Avalon Slave 总线将period 和duty 值从Nios II 应用程序
传送到组件逻辑中。
3．Writedata：写数据。通过此数据线传送period 和duty 值。
4．Address：本例中有两个寄存器，因此可用一根地址线表示。
5．全局信号。本例中PWM 的输出用来驱动LED 灯显示，这个信号不属于Avalon 接
口信号。
