pwm的占空比和死区时间可调的Verilog HDL程序设计和测试-duty cycle of pwm and adjustable dead time of the Verilog HDL design and testing procedures

产生正弦波、方波、锯齿波，频率可调，方波占空比可调-Generated sine wave, square wave, sawtooth wave, frequency adjustable, adjustable duty cycle square wave

四路PWM输出控制器，输入频率5OMHz，输出频率调，输入数据实现占空比控制。-Four-way controller PWM output, input frequency 5OMHz, tune output frequency, duty cycle control of the realization of the input data.
