File Information
Description	This tutorial starts with a simple conceptual model of an analog Phase-Locked Loop (PLL). Through elaboration it ends at a model of an all digital and fixed-point phase-locked loop. The final model can serve a starting point for code generation (both ANSI C or synthesizable HDL). The step-wise elaboration of the model illustrates how Simulink® forms the basis a model-based design where continuous verification of the model reduces errors.
Required Products	Communications Blockset Communications System Toolbox Control System Toolbox Fixed-Point Toolbox DSP System Toolbox Signal Processing Toolbox SimPowerSystems Simulink Simulink Fixed Point Stateflow
MATLAB release	MATLAB 7.4 (R2007a)
Other requirements	Not all the products are required for all the models (see the published m-file for more details)

08 May 2009	Niceseb cheung	cp_pll has run time error "Error reported by S-function 'scominhshape' in cppll/Continous time VCO/Inherit Shape1" Input and output frame status or dimension are invalid. ? Also how to plot the 2 input scope on top of each other so I can see the phase offset?
23 Nov 2009	M. Cirillo	You can plot the two curves on one axis using a Mux (in Signal Routing). Run the Mux output to the scope and you'll be able to see the offset more clearly.
01 Oct 2010	Noura Ben Ameur	i have matlab 7.0 release and the file "dpll.m" does'nt work due to "NCO" block. How can i do?
