Simulating oscillators using SPICE

SPICE generation of the output signals from electronic oscillator circuits is obtained by transient analysis. Simulation success is software specific and depends upon how the transient analysis function is configured. Different tricks, which are oscillator configuration specific, may be applied to achieve simulation output. In the final analysis, one must remember that simulation is not a complete and full replacement for circuit construction and testing. Accurate analysis is given for resonant or relaxation circuits.
