help with 8x8 common anode rgb matrix panel

well here is my hardware config, im just trying for a basic simulation in LT spice

im trying to simplify the panel so that I can observe voltage, current, and power waveforms.

So my question is, for a common anode matrix 8x8
do you hook up a voltage DC source at the anodes
and what do you hook up to the RGB pins.

for a simple simulation, I do not want to make the circuit from the chips im using for my project, i just want to simulate a simple 8x8 common anode matrix and understand the waveforms.
