Event-Driven Simulation of the CP-PLL in Frequency Hopping Systems

为了快速仿真单片集成跳频系统中的电荷泵锁相环 ,在比较几种常见仿真方法的基础上 ,重点介绍了电荷泵锁相环的事件驱动模型 ,并针对这种模型的具体实现提出了一些改进。改进后的模型主要应用于跳频系统中频率合成锁相环的稳定性和建立时间的快速仿真。

In order to simulate charge pump PLL in frequency hopping systems, several methods are introduced and compared. The emphasis is on the event-driven model which can simulate the charge pump PLL quickly and efficiently. When the model is used to simulate the stability and setting time of the charge pump PLL, some improvements are made to run it faster. Other issues such as the relation between different models and some detailed aspects of implementation are also discussed.
