PSpice Reference Guide Glossary ABM analog behavioral modeling AKO “A Kind Of” symbol. Symbols must either contain graphics or refer to an AKO symbol. The AKO defines the symbol in terms of the graphics and pins of another part. Both must exist in the same Symbol Library file. alias An alias relates local schematic names for parts and signals to netlist names (simulation devices and nodes). An alias is an exact electrical equivalent that can be used to reference a symbol. A command that sets up equivalences between pin names or net names and node names. As a command, it is the setup equivalences between node names and pin names or net names. annotation Annotation is a means by which parts are labeled when they are placed, either automatically or manually. annotation symbol An annotation symbol has no electrical significance, and is used to clarify, point out, or define items on the schematic. argument A value or an expression used with an operator or passed to a subprogram (subroutine, procedure, or function). attributes Attributes are special characteristics (a name and an associated value) contained in a part instance or definition. For example, a MOSFET may contain specific length and width parameters which are represented as attributes on the symbol or part. Attributes may be changed through the Property Editor and/or the Parts Editor. bus A bus is a collection of homogeneously named signals. call To transfer a program execution to some section of code (usually a subroutine of some sort), while saving the necessary information to allow execution to resume at the calling point when the call section has completed execution.
