步进电机使用中常需要增减速控制,为此,针对驱动步进电机的脉冲,设计了一款脉冲频率控制电路,设计借鉴了直接数字频率合成（DDS）中相位累加的变频思想,使输出脉冲频率做到了线性递增和递减,且增频斜率可控,该设计为步进电机的实际应用提供了方便.电路逻辑功能采用VHDL语言描述,充分发挥了EDA技术优势.波形仿真结果表明,功能完全达到设计期望.

Speed control is often required for stepping motor usage,therefore,a pulse frequency control circuit was designed on account of pulse which drives stepping motor.This design was based on the idea of frequency conversion by phase accumulation from DDS（Direct Digital Synthesizer）,which realized that the output pulse frequency increase and decrease linearly,and the slope of increasing/decreasing frequency is controllable.This design brought convenience to the practical usage of stepping motors.The circuit logic function used VHDL language,which has EDA technology advantage.The wave simulation result shows the function had met design expectation.
