Glossary
ABM
Analog behavioral model. A view of a hierarchical schematic used for
analysis. See also View.
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 exact electrical equivalent that can be used to reference a symbol.
annotation
A means by which parts are labeled when they are placed, either
automatically or manually.
annotation symbols
A symbol with no electrical significance, used to clarify, point out or
define items on the schematic.
attribute
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 that are represented as attributes
on the symbol or part. Attributes may be changed through the
schematic editor, the symbol editor, or both.
back annotation
Annotation of a schematic using an ECO file from the selected layout
editor.
block
A user defined rectangle placed on a schematic. It is used to represent
or hold the place for a collection of circuitry. The block is treated as a
black box by PSpice Schematics. PSpice Schematics is aware of the
connections going into and out of the block, but ignores the contents of
the block until netlisting.
