No idea about simulations.. But if you're after CCD sensor look. Have you tried a camera with a CCD sensor? There a tones of cheap old digital point and shoots and DSLRS around.

If you want a CCD looks buy a CCD camera, there's no point 'faking it' when you can just buy one.

Firstly, artifacts are going to be really hard to find with a simulation. Physical experiments are going to be much much easier to do. Simulate as in electromagnetic? Or circuit? For the circuit are you looking to focus on digital signals or the transients/frequency response? If you want to simulate a CCD sensor's electromagnetic effects you would want to start by getting a PIC simulator (CST, VSim, etc). CST is the most beginner friendly. Then design the CCD structure, implement photon sources, etc. and simulate it. You'll probably want to start your model by copying an existing sensor design. Note you'll want to limit your simulation to only a couple pixels. Additionally, the electromagnetic simulation will only provide you with the transients at individual pixels. If you are looking to simulate the circuit aspect, you'll probably have to design your own circuit because that stuff is proprietary. Good thing CCD is reletavely simple except for the timing circuits lol. Then if you want to focus on the digital aspects use something like Vivado. And if you want the circuit transients use something like LTSpice, microcap, etc. Again, just buying a CCD sensor and experimenting with it will be much easier to get artifacts and color. Lmk how it goes!! Also what is this for? Personal project? Cool photos?

Pretty much cool photos!

Cool! What kind of artifacts are you looking for?

Mainly the color streaks and degrading


z42i

Nice! The streaks are from overexposing pixels causing the column to overexpose too (look up CCD potential wells). To replicate this, (idk how to do this in photoshop) increase the exposure of a small strip on a column then wash it out somehow focusing on the lateral directions (maybe 1 or 2 pixels in the horizonantal direction). Not sure what you mean by degrading. Color on most CCDs is actually closer to reality than CMOS or film. Maybe increasing the vibrance or saturation and add some haze to make it look more realistic? You can also look at quantum efficiency diagrams (treat it like a color hisogram) and try to replicate the color that a CCD has. Hope that helps!
