Presentation Transcript

  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 Simulate Generate Netlist (SPICE Netlist Different flavors Quite similar) Schematic Entry (Common Data format: EDIF)

  4. Bias Point and DC sweep Bias Point Results Single Operating point DC Sweep Results Output as a function of Vin Vo Vin

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

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