Glossary

card : A logical SPICE input line. A card may be extended through the use of the “+” sign in SPICE, thereby allowing it to take up multiple lines in a SPICE deck.

code model : A model of a device, function, component, etc. which is based solely on a C programming language-based function. In addition to the code models included with the XSPICE simulator, you can use code models that you develop for circuit modeling.

deck : A collection of SPICE cards which together specify all input information required in order to perform an analysis. A “deck” of “cards” will in fact be contained within a file on the host computer system.

element card : A single, logical line in an XSPICE circuit description deck which describes a circuit element. Circuit elements are connected to each other to form circuits (e.g., a logical card which describes a resistor, such as R1 2 0 10K, is an element card).

instance : A unique occurrence of a circuit element. See “element card”, in which the instance “R1” is specified as a unique element (instance) in a hypothetical circuit description.

macro: A macro, in the context of this document, refers to a C language macro which supports the construction of user-defined models by simplifying input/output and parameterpassing operations within the Model Definition File.

.mod : Refers to the Model Definition File. The file suffix reflects the file-name of the model definition file: cfunc.mod.

.model: Refers to a model card associated with an element card in XSPICE. A model card allows for data defining an instance to be conveniently located in the XSPICE deck such that the general layout of the elements is more readable.

Nutmeg : The SPICE3C1 default post-processor. This provides a simple stand-alone simulator interface which can be used with the ATESSE simulator (see referenced documents section for additional information on Nutmeg)

.subcircuit : A “device” within an XSPICE deck which is defined in terms of a group of element cards and which can be referenced in other parts of the XSPICE deck through element cards.
