一个在CPLD，EPM70128上实现的PWM控制源程序。

说明：  潘松那本书上用vhdl语言描述的16位并入并处加法器(Pan book vhdl language used to describe the 16-bit adder into his)

An Alarm Project Writen in VHDL for FPGA Devices

此程序描述了数字电路中与门的逻辑功能。所采取的硬件描述语言为VHDL。程序结构采用了dataflow的写法。请大家仔细阅读。本程序已通过了Altera quartus的验证。确保准确无误。

说明：  Any change to the value of Mresults in immediate and phase-continuous changes in the output frequency
