An alternative way is to use a schematic entry program such as OrCAD CAPTURE. This file is called the SPICE input file or source file and has been described somewhere else. One way is to enter the circuit description as a text file in terms of the elements, connections, the models of the elements and the type of analysis. PSpice with OrCAD Capture (release 9.2 Lite edition) Before one can simulate a circuit one needs to specify the circuit configuration. The circuit can contain the following components: Independent and dependent voltage and current sources Resistors Capacitors Inductors Mutual inductors Transmission lines Operational amplifiers Switches Diodes Bipolar transistors MOS transistors JFET MESFET Digital gates and other components (see users manual). All analyses can be done at different temperatures. This makes it a useful tool for a wide range of analog and digital applications. Noise analysis Parametric analysis Monte Carlo Analysis In addition, PSpice has analog and digital libraries of standard components (such as NAND, NOR, flip-flops, MUXes, FPGA, PLDs and many more digital components, ). Linear AC Analysis: calculates the output as a function of frequency. Non-linear transient and Fourier analysis: calculates the voltage and current as a function of time when a large signal is applied Fourier analysis gives the frequency spectrum. Here are the most important ones: Non-linear DC analysis: calculates the DC transfer curve. SPICE can do several types of circuit analyses. Information about Pspice AD is available from the OrCAD website: The PSpice Light version has the following limitations: circuits have a maximum of 64 nodes, 10 transistors and 2 operational amplifiers.
The OrCAD student edition is called PSpice AD Lite. A student version (with limited capabilities) comes with various textbooks.
PSpice is a PC version of SPICE (which is currently available from OrCAD Corp. It was for this reason that SPICE was originally developed at the Electronics Research Laboratory of the University of California, Berkeley (1975), as its name implies: 1ΔΆ Simulation Program for Integrated Circuits Emphasis. This is of particular importance for integrated circuits.
INTRODUCTION SPICE is a powerful general purpose analog and mixed-mode circuit simulator that is used to verify circuit designs and to predict the circuit behavior.
