Complex is a very tricky question.

I think people already simulated a worm's neural nets, but we simulated just high level abstractions of what those "simple", 200 neuron networks are. Sure, by simulation tickling part of the worm, we get the exact reflex reactions a living worm would, but surely the simulated worm does not have sensations, I can do the same worm simulation with if-else statements, just because I see a worm realistically wiggling on the screen I do not believe it can suffer pain, or else I would never play Worms Armageddon.

I believe there is something to the chemical processes themselves that we will not be able to replicate in pure software.

That brings the question, what if we could simulate the quantum particles themselves, not just some high level representation of cells, would that simulated being have sensations/feelings?

If we perfectly simulated, at the quantum particle level a cat, would the cat behave like a real cat?

That is mindboggling to me; unfortunately we cannot do that yet.
