The name of the element must be within the range of one to eight characters in length, and they may include numbers or letters. The first letter of the element’s name tells PSPICE the nature of the element, be it a resistor, capacitor, voltage source and so on. This task is accomplished by first giving a name to each and every circuit element. Each element is described using one line in the PSPICE program, where each piece of information about the element is separated by a tab. In addition to this, there must be a node between each element in series, and one of the nodes must be labeled as a reference node, or ground, denoted by the number "0".ĭescribing the circuit elements is a very important task in PSPICE. Therefore, before typing in a PSPICE program, the user must redraw the desired circuit clearly indicating the circuit nodes and which elements are connected to them. The location of the elements within a circuit needs to be specified according to which nodes they are connected. Documentation, including the mention of circuit elements, placed in a portion of the program that PSPICE ignores allows the user to keep track of the circuit’s purpose and any dummy variables needed for PSPICE to properly analyze the circuit. If further documentation is deemed necessary, an asterix, *, placed at the beginning of any line will tell PSPICE to ignore that line, and a comma placed after a PSPICE command will tell PSPICE to ignore the remainder of that line. This is necessary because PSPICE ignores the first line of all programs, and it is also practical for documentation purposes. Although PSPICE may seem like it is more complicated than it is worth for solving simple circuits, PSPICE can be incredibly useful if properly employed for solving circuits that require complex mathematics.įirst of all, the PSPICE document must have a title. Understanding the basic nature of the circuit in question is also essential for interpreting the results given after PSPICE has analyzed the circuit. For this reason, those who use PSPICE for circuit analysis, must fully understand the elements of a circuit and how these elements function within the circuit so that the correct information is input into the PSPICE program. Since PSPICE cannot know the nature of the user’s desired circuit by visual inspection of the schematic, the user must follow a set of standard guidelines to translate the circuit from a schematic into a form that the program can understand. PSPICE is able to calculate these values by solving simultaneous equations formulated from the information that has been input by the user. This program is designed to calculate the voltages and currents of specified circuit nodes and/or elements in using dc, ac, or transient analysis.
