SPICE:
The
rapid change in the field of electronics engineering is paralleled by programs
that use the computer’s increased capabilities in the solution of both
traditional and novel problems. With the availability of tools for
computer-aided circuit analysis, circuits of great complexity can be designed
and analyzed within a shorter time and with less effort compared to the
traditional methods. SPICE is a computer-aided simulation program that enables
the design and simulation of circuits. SPICE is the acronym for a Simulation
Program with Integrated Circuit Emphasis.
Fundamentals
of SPICE Programming:
Programming a circuit simulation with SPICE is much like
programming in any other computer language: you must type the commands as text
in a file, save that file to the computer's hard drive, and then process the
contents of that file with a program (compiler or interpreter) that understands
such commands.
SPICE
is a General- Purpose circuit simulation program for non-linear DC, nonlinear transient
and linear AC analysis. Circuits may contain Resistors, capacitors, inductors,
mutual inductors, independent voltage and current sources, four types of
dependent sources, transmission lines, switches, and several semiconductor
devices: including diodes, BJTs, JFETs, MESFETs, and MOSFETs. Circuits with
large numbers of all types of components can be simulated.
In PSPICE the program we run in order to draw circuit schematics
is called CAPTURE. The program that will let us run simulations and see graphic
results is called PSPICE. You can run simulation from the program where your
schematic is. There are a lot of things we can do with PSPICE, but the most
important things for you to learn are :
1. Design and draw circuits
2. Simulate circuits
3. Analyze simulation results (Probe for older versions)
For this course you will not need the full capacity of CAPTURE.
The devices that we will use are resistors, inductors, capacitors and various
independent/dependent sources. It is good to know that CAPTURE has extensive
symbol libraries and includes a fully integrated symbol editor for creating
your own symbols or modifying existing symbols :
The main tasks in CAPTURE are :
1. Creating and editing designs
2. Creating and editing symbols
3. Creating and editing
hierarchical designs
4. Preparing your design for
simulation.
