Included in this collection is a working programming example, provided in each supported language. The SPICE statements to define the above coupled coils are as follows. Feel free to “copy” and “paste” any of the netlists to your own SPICE source file for analysis and/or modification. If the results contain errors, start up the text editing program again and modify the netlist. versions of PSpice allow you to ask for a current through a resistor without or books listed at the end of It is likely that the old URL for this PSpice tutorial will disappear on August 31, 2015. The circuit of a Differential Amplifier. The easiest Solution: a simple ideal Transformer 35 6.2.2. As an early public domain software program with source code available, SPICE … SPICE allows you to define a collection of elements as a subcircuit (e.g. If your trial run produces error messages or results that are obviously incorrect, you need to re-invoke the text editing program and modify the netlist. It then lists the input parameters (the lines of the source file), followed by a display of DC voltage readings from each node (reference number) to ground (always reference number 0). SPICE file: "diff_amp.sp" * Anant Agarwal and Jeffrey H. Lang, * Foundations of Analog and Digital Electronic Circuits, * Elsevier Inc., 2005. Independent and dependent voltage and current sources, Digital gates (PSpice, version 5.4 and up). 220-spice-notes.tex Page 6 Powers of Ten The following abbreviations for powers of ten are recognized by spice. 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. respectively. Some ), the “<” symbol redirects the contents of the source file to the SPICE interpreter, and example.cir is the name of the source file for this circuit example. Sinusoidal sources will be used in a subsequent tutorial. The tutorial should also help signal integrity engineers to get quick codes for copy paste and modify. This is very useful for several reasons. 2. In its original form you tell Spice what elements are in the circuit (resistors, capacitors, etc. Circuit architecture is specified by assigning numbers to each component’s connection points in each line, connections between components designated by common numbers. For an example of the model parameters of the Save this file into a folder called “Tutorial”. Spice always assigns a positive reference mark to the 1st node and uses However, for integrated circuit simulations one need to specify Noise analysis 5.

Spice uses the node-voltage analysis. an operational amplifier) and to insert this description into the overall circuit (as you would do for any other element). It is written in C, uses the same netlist syntax, and added X Window System plotting. For more information, please refer to the SPICE user's manual Here is a sample of that same output, redirected to a text file (spice < example.cir > example.txt), then trimmed down judiciously with a text editor for final presentation and printed: One of the very nice things about SPICE is that both input and output formats are plain-text, which is the most universal and easy-to-edit electronic format around. SPICE. It is worthwhile to take a look at some simple simulation using hspice. Here PSICE stands for simulation program for simulation circuits emphasis. In many cases, we need to use switches that open and close at certain times or under certain conditions of voltage or current. characteristics, such as the Drain current ids versus the Drain-source Short Tutorial on PSpice. function of time when a large signal is applied. In an interpreted computer language, the computer holds a special program called an interpreter that translates the program you wrote (the so-called source file) into the computer’s own language, on the fly, as its being executed: In a compiled computer language, the program you wrote is translated all at once into the computer’s own language by a special program called a compiler. This tutorial will cover the basics of using LTspice IV, a free integrated circuit simulator. which is a damped sinusoidal voltage source: Vname = VO + VA exp[-THETA.

The format is as follows: An example of an inverting opamp circuit using the subcircuit The plot will show up in a separate window, which has some analysis tools that might be handy in certain situations. Spice start options: Select ngspice or another spice; file select options: Start ngspice automatically in interactive or in batch mode, or do not start automatically and wait for user to start ngspice from main window; batch start options: If 'Start batch' from main window is selected, start either with rawfile (e.g. It is the result of combining existing SPICE features with some extra analyses, modeling methods and device simulation features. An example of the first approach (linear AC model) is given below for In order for a computer to be able to understand the SPICE instructions you type, it must have the SPICE program (interpreter) installed: SPICE source files are commonly referred to as “netlists,” although they are sometimes known as “decks” with each line in the file being called a “card.” Cute, don’t you think? a) Copy the following SPICE code and save it as a .sp file. a word processor to edit the output, deleting any unnecessary banners and messages, even specifying alternative fonts to highlight the headings and/or data for a more polished appearance. Here is an example of an undelayed cosine This LTspice Tutorial digs deeper into circuit analysis with LTspice ®. Line 1 is a comment, as always. The above paramters are usually sufficient when specifying discrete How can I turn the PSpice code (as a *.cir file) into the schematic capture? A typical SPICE output is several screens worth of information, so you might want to look it over with a slight modification of the command: This alternative “pipes” the text output of SPICE to the “more” utility, which allows only one page to be displayed at a time. Line 1 is a comment, as always. SPICE allows you to define a collection of elements as a subcircuit (e.g. Sinusoidal sources will be used in a subsequent tutorial. between the sinusoid and cosine. The tutorial starts under the assumption that the demo version of … Here are themost important ones: 1. Feel free to “copy” and “paste” any of the netlists to your own SPICE source file for analysis and/or modification. SPICE3 was developed by Thomas Quarles (with A. Richard Newton as advisor) in 1989. Compose a new netlist with a text editing program.

As an example, the model parameters for a 1N4148 commercial diode (See Chapter 2’s Computer Simulation of Electric Circuits for more information on netlists in SPICE.). 6.5 JFET model: 2N5459. classes. First developed at UC Berkeley, it is the origin of most modern simulators. In First tutorial, you will learn how to download and install this simulation and circuit design software with step by step guide. Each element in the circuit (vdd, R1, and R2) is identified by node numbers and a value. At the start of the tutorial a brief introduction regarding rectifiers (both full wave and half wave) is provided. The cycle starts when you first invoke the text editing program and make your first draft of the netlist. A FIG 1 shows the jig of the LTC3878 external FET buck converter with a resistive load of 80mOhms. Being that the direct SPICE output is plain ASCII text, such a file will be universally interpretable on any computer whether SPICE is installed on it or not. Each element in the circuit (vdd, R1, and R2) is identified by node numbers and a value. The last FORTRAN version of SPICE is 2G.6 in 1983. This is followed by a list of current readings through each voltage source (in this case there’s only one, v1). As in general programming, the source file you create for SPICE must follow certain conventions of programming. SPICE can do several types of circuit analyses. 9 List of Code Models Available We can get a list of all code models available in Spice Opus by typing: siminfo all at Spice Opus prompt. There is a cycle of steps to be followed in using SPICE to analyze a circuit. The netlist file format required by SPICE is quite simple. What this means (in English) is that the text output of SPICE is halted after one screen-full, and waits until the user presses a keyboard key to display the next screen-full of text. SPICE doesn’t care what you name it, so long as it has a name compatible with the filesystem of your computer (for old MS-DOS machines, for example, the filename must be no more than 8 characters in length, with a 3 character extension, and no spaces or other non-alphanumerical characters). SPICE Simulation Program with Integrated Circuit Emphasis • Originally developed at EE Berkeley • Uses mathematical models to describe circuit elements • SPICE3 is the latest variant. .DC Sweep), 5.2 HSpice example (.TF analysis and .DC Sweep), 5.3 Mutual Inductor (Transformer;Transient Operational Amplifiers (incl. HOW TO SPECIFY CIRCUIT TOPOLOGY AND ANALYSIS? and also the unknown, the ratio of output variable to input variable (gain or tranfer gain), the resistance with respect to the input source, the resistance with respect to the output terminals. PSPICE tutorial: a simple DC circuit We will learn some of the basic maneuvers of using the Cadence schematic capture program and PSPice engine through a simple example -- a diode rectifier circuit. This tutorial provides a basic introduction to the use of netlists in pspice for students in the Electrical and Computer Engineering Department at Cal Poly Pomona. For a final presentation, it might be nice to trim all the unnecessary text and leave only what matters. Practically any computer will be able to edit and display this format, even if the SPICE program itself is not resident on that computer. SPICE requires that the first line be a title text. are optional. Brief Spice Tutorial ECE 3110, University of Utah, Fall 2002 By now, you have used SPICE in at least one other class. Netlists are created by a person like yourself typing instructions line-by-line using a word processor or text editor. The following circuits are pre-tested netlists for SPICE 2g6, complete with short descriptions when necessary. The SPICE comment character is the asterisk, "*".
