MNAME is the model name. A subcircuit is defined by a. There can be any number of external nodes with arbitrary names but not 0. The node names used inside the subcircuit are strictly local, except for node 0 which is always global. Refer to section 2.

Numbers can be integers, or floating points. As an example, one can specify a capacitor of picofarad in the following ways: P, p, pF; pFarad; E; 0. Spice uses the node-voltage analysis. It solves for the unknown node voltages and also the unknown currents through independent voltage sources. This gives us a way to find currents flowing in elements: one has to ask for the current through a voltage source. Thus one can insert an independent voltage source of zero value in series with the element in which one wants to know the current, as shown in the example below: The value of the current will be positive if it flows from the positive to the negative terminal through the source, as in the above example.
Some versions of PSpice allow you to ask for a current through a resistor without using a voltage source EX: I R1 gives the current in the resistor R1. NC1 and NC2 are the positive and negative terminals of the controlling voltage source, respectively. Vcontrol is the zero value voltage source used to measure the controlling current the positive current flows into the positive terminal of the controlling voltage source!
Examples: F1 0 3 Vmeas 0. Resistors d. N2 is the negative node. IC is the initial condition DC voltage or current. If not specified, it is assumed to be zero. In case of an inductor, the current flows from N1 to N2.

Fekora Part 1 Posted by Michael Shimniok. Any help would be appreciated. High-Level Synchronization for Data Links Learn about for lack of a better term packetization, a technique that facilitates robust data transfer in optical, RF, and long-distance-digital communication systems. The first time you launch MacSpice it will tutlrial a working directory inside your Documents folder and will assume that any filename which does not specify an absolute path refers to files in this folder.

SPICE - A Brief Tutorial
Miramar MacSpice is compatible with, and a descendant of, Berkeley Spice 3f5. Milestone 4 Circuit Your name or email address: Explain why you would expect to find at least one line starting. The interface will puzzle you at first. I want to use modeling to analyze the existing circuit and to help me come up with a better design. Since your screen-shot does not look like Mxcspice, my first advice is to go get LTspice.
