I was slightly disappointed by upverter, the simulation tool is basically useless, but it's the mot important feature in design. And the schematics is buggy (like when you rotate resistors). I really hope they fix those basics before starting some new features (but I understand they are working on a API already). It's so much important for mac users like me who have no real design tools.

Personally I've never found simulation tools all that useful. Too many components that can't be simulated, like microcontrollers and simple components that just don't have a model available.

Perhaps you've been using better tools than me! What sort of tools do you use that make you think simulation is the most important feature?

I'm starting again electronics, but I was trying to design the power stage of a BLDC motor. So it's mostly about MOSFET half-bridges and their driving. In this case you have to check you are using every components in their ratings. If you are designing a battery-operated system it's also good to know about power consumption of your output stage.

And I totally agree about the components, if I add a connector for PCB routing purpose, I should be able to simulate anyways.
