SPICE

SPICE stands for Simulation Program with Integrated Circuit Emphasis.

SPICE originates from the EECS Department of the University of California at Berkeley.

The Origins of SPICE

– SPICE developed in the 1970’s• SPICE is a general-purpose circuit

simulation program for nonlinear dc, nonlinear transient, and linear ac analyses.

– Developed to save money• Simulation of circuits, not physically

building• Transistor sizes–Microprocessors vs. 2N2222

This is how!

• New user interface• Graphical circuit

diagrams• Variation of simulation

parameters with a few clicks

Features

• First Look at Capture• Place Parts• Rotate and Move

components• Change the Voltage and

Wire• Placing the Ground• The Completed Circuit• Edit the Simulation Profile• Running the Simulation
