@DerKommissar Yea, basically you only simulate modules. Simulating the entire board is not feasible with most boards, although in RF designs it's more common to do at least a specific type of simulation before making a prototype. You really don't want to fry your first prototype of a complex filter, or worse, PSU, by shorting it with the RF coming from the antennae next to it, for example.
So in specific situations there are specific scenario's you should test against.
Afar from that, just simulate the module, prototype the module, put module on board, see what happens.
@all Thanks for the response. I got a plan now, so half the battle has been fought already.
