1 IEEE Spice Seminar Simulation Program with Integrated Circuit Emphasis

2 Examples of Types of Spice Simulations Bias Point DC Sweep Transient Analysis AC sweep/Noise Secondary (nested) sweeps Parametric Temperature Monte Carlo

3 Generating a Netlist SPICE Netlist Text file used for simulation Schematic Entry (Common Data format: EDIF) Generate Netlist (SPICE Netlist Different flavors Quite similar) Simulate

4 Bias Point and DC sweep Bias PointResults DC SweepResults Single Operating point Output as a function of Vin Vo Vin

5 Transient and AC Sweep TransientResults AC SweepResults Output as a function of time Multiple sinusoidal inputs each with a different frequency Time varying inputs (ex. Sinusoidal, digital clock) Vo freq t t Output as a function of freq.

6 Key Difference Between AC Sweep and the others (Transient Analysis, DC Sweep and Bias Point Analysis) Transient Output Does NOT saturate! Vout = Ao Vin Vin = 1 => Vout = Ao Output saturates at +/-10V Vo(s) = Ao(s) freq t Cos(2  f t) f = 1kHz Ao=100 1K Hz 100 AC Sweep
