Square wave voltammetry

I am doing a project to conduct square wave voltammetry on an electrochemical cell. To test the program, I wish to build an equivalent circuit such as the Randles circuit. Does anybody have suggestions regarding the method to design the circuit and parameter values to be considered?

Why are you applying a square wave? Just apply a voltage and measure the current.

Well, I am doing an electrochemical analysis using square wave voltammetry. Before testing on a three-electrode system, I thought of applying it on an equivalent circuit and measure the current.
