Simulation tool for complex embedded system

[mehdix]

Hello,
I want to build an android-based embedded system. Is there any simulation tool with the ability of describing and simulating the design before hardware prototyping? (something that Proteus does for simpler parts and ICs).
I need the tool to model one or more SoCs (Tegra, Exynos, Snaopargon,...) to conduct a design space exploration to find the best configuration.
I've already found Qemu, but it seems that a new configuration can not be described in it.
Thanks!

I don't really understand what exactly you intend to simulate - if you're looking for some kind of combined multi vendor hardware & software simulator I'm pretty sure that there's no such thing.

Why not just use a good evaluation board once you choose your target device? That's what designers usually do...
