![]() ![]() dc analysis option is invoked, the default voltage printouts for each node (to ground) disappears, so we end up having to explicitly specify them in the. print card analysis to print out voltages between any two points we desire. dc analysis card and specifying source V 1 from 24 volts to 24 volts in 1 step (in other words, 24 volts steady), we can use the. Voltage source currents name current v1 -1.425E-03 v2 -6.485E-04Įxample multiple-source DC resistor network circuit, part 2īy adding a. plot card, the output for this netlist will only display voltages for nodes 1, 2, and 3 (with reference to node 0, of course). ![]() So don’t be surprised when you run a simulation on your own and find that the output doesn’t exactly look like what I have shown here! Example multiple-source DC resistor network circuit, part 1 Typical SPICE outputs contain lots of headers and summary information not necessarily germane to the task at hand. I do this primarily to save space in this document. My goal here is twofold: to give practical examples of SPICE netlist design to further understanding of SPICE netlist syntax, and to show how simple and compact SPICE netlists can be in analyzing simple circuits.Īll output listings for these examples have been “trimmed” of extraneous information, giving you the most succinct presentation of the SPICE output as possible. (See Chapter 2’s Computer Simulation of Electric Circuits for more information on netlists in SPICE.)įeel free to “copy” and “paste” any of the netlists to your own SPICE source file for analysis and/or modification. ![]() The following circuits are pre-tested netlists for SPICE 2g6, complete with short descriptions when necessary. ![]()
