Introduction to SPICE-Electronic Circuit Simulation

SPICE-Simulation Program for Integrated Circuit Emphasis

SPICE is an Electronic circuit simulator used to verify/predict circuit behaviors. It was developed at the electronic research lab of University of California, Berkeley.

A circuit must be presented to SPICE in the form of netlist. Netlist is a text description of all circuit elements and their corresponding connections.

Simulation tools allows user to draw circuit schematics and automatically translate the circuit diagrams into netlist.

SPICE Model:

Text description of a circuit component used by the SPICE simulator. The extension for the SPICE model file may be in .cir/.mod. .lip is library of .mod files.

The model files can be obtained from corresponding part manufacturer

Model file for Resistor:

Rname n1 n2 value

R120    2   3    100

Analysis using SPICE:

1. DC Analysis

2. AC Analysis

3. Transient Analysis

4. Distortion Analysis

5. Noise Analysis

Some of the Popular Simulation Tools:

1. PSPICE from Cadence

2. Multisim from National Instruments

3. TINA from Design Soft

4. Saber from Synopsys

5. LTSpice from Linear
