PLLSim - An Ultra Fast Bang-Bang Phase Locked Loop Simulation Tool

- This paper presents a simulation tool targeted specifically at bang-bang type phase locked loop systems. The aim of this simulator is to quickly and accurately predict important PLL transient characteristics such as capture range, locking time, and jitter. We present a behavioral model for bang-bang type PLLs, and show how the application of this model in a simulator can speed up simulation time by four to five orders of magnitude. With this performance, Monte-Carlo simulation techniques become not only feasible, but convenient. The simulator also models the major non-idealities typical of phase locked loop systems. The accuracy of the simulator is confirmed via detailed analysis and comparison with Matlab Simulink based models.
