From: Ahmed on 1 Jun 2010 14:47 Hi, I am trying to simulate jitter performance of an analog PLL based Clock and data recovery. I have two questions: 1. Is it possible to implement an analog filter in Simulink for event-driven simulation? 2. For event diven simulation, can i only use State flow toolbox or do i need to use Sim-event as well? Thank you

I have two questions: > > 1. Is it possible to implement an analog filter in Simulink for event-driven simulation? Yes, it is possible. The following two SimEvents demos may serve as examples 1. "Bit Timing Recovery Using Fixed-Rate Resampling and SimEvents" -- sedemo_timrecresample.mdl 2. "Delayed Function Calls in Pulse width Modulation" -- sedemo_pulse_width_mod.mdl To access these demos, you need to have SimEvents and Communication toolbox installed. You may want to request a trial version of SimEvents at http://www.mathworks.com/products/simevents/ > 2. For event diven simulation, can i only use State flow toolbox or do i need to use Sim-event as well? For some cases, you may get around by only using state flow toolbox to do event driven simulation. However, in general you should use SimEvents toolbox to do typical discrete event simulation. > > Thank you |
