    I have constructed my very first circuit on a breadboard. It is 555 timer, working in astable mode - the metronome; so it produces hi-impulses periodically. Now I will be happy if it's possible to simulate this circuit in SPICE. But I have no idea "how can I simulate 555 IC"?

    Is it possible in SPICE to simulate ICs at all? I suggest "Yes", but in this case: "where can I find a spice file for any Integrated Circuit"?

    The first port of call is always the manufacturer. Failing that, google is the next step.

    TI has a transistor level model (subcircuit) for 555, you can go there and search for it.
