The Proteus suite (http://www.labcenter.co.uk/index_uk.htm) will simulate
PICs and do spice simulation of the rest of the circuit, they also simulate
lots of non-trivial digital chips such as some eeproms and lcds. It will
even integrate into mplab letting you step through your program while the
rest of your circuit and its interactions with the processor are simulated
in it.
