Someone did try using SPICE to simulate the 6502, and it was much slower than the real hardware:

it took about 30 mins to run through reset and then 20mins to do 10 cycles of instructions.

That's to be expected. Transient SPICE analyses can become really slow for larger circuits (couple real-ps/CPU-s for analog circuits that work with a few dozen MHz).
