Principles of Electric Circuits, Sixth Edition
CHAPTER 1 ■ INTRODUCTION TO PSpice
The speed and power of the puter make it suitable as a simulation and
analysis tool. Using the proper simulation programs, savings in time and cost can usu-
ally be realized in the design, building, and testing of electronic circuits. With simula-
tion software, you can analyze the operation of a prototype circuit and identify design
flaws or performance problems before the circuit is actually constructed.
It is important to keep in mind that as powerful as modern simulation software is, you
must still have a thorough understanding of circuit theory and the concepts and tech-
niques of circuit analysis. The software is simply an additional tool that can be used to
extend your analysis capabilities; it cannot interpret analysis results or design circuits
for you.
pleting this tutorial, you should be able to
■ Define SPICE and express electrical quantities in PSpice format
■ Describe a PSpice circuit file
■ Use the proper PSpice designations for several ponents
■ ponent values in three different notations
PSpice
The standard for analog electronic circuit simulation and analysis is SPICE (Simulation
Program with Integrated Circuit Emphasis). PSpice from OrCad-MicroSim Corporation is
the PC-based version of SPICE. Although the capabilities of PSpice go far beyond what
most technicians require, it performs many technician-oriented tasks very well, while
requiring only a basic understanding of the program.
With PSpice, you can solve for voltages and currents in simple resistive and reac-
tive circuits, or you can analyze the detailed performance plex circuits. PSpice
allows you to concentrate on learning circuit concepts rather than spending a lot of time
on tedious calculations. It is, however, important that you know how to do circuit calcu-
lations.
