Base on the boost principle analysis and circuit design in the beginning , the author simulated the sub - block circuits and whole chip circuit by applying eda tools hspice , the simulation result indicates that the ic has achieved the expectation of the function target and the electrical characteristics . although there were unavoidable disadvantages of this project , it is a worthwhile and valuable experience 在完成电路原理分析与电路设计的基础之上,作者应用eda软件hspice对各个子电路模块和整体电路进行了功能仿真及量化模拟,仿真结果均达到或优于预定指标,验证了作者在第二章中阐述的直流升压boost电路的设计理论,是设计理论与实践相结合的一次有价值的尝试。
