I have recently used LTSpice IV for circuit analysis. It is particularly good for switch-mode power supplies, but I've used it for a variety of other things.

For layout of PCBs I use Sprint Layout

The former tool is free, the latter is quite inexpensive (as these things go). Neither are up to large commercial products, but for small projects they're great -- well I think so.
