selection area
When drawing or editing a schematic or symbol, the area identified
and enclosed by a region-of-interest (ROI) box for the purpose of
performing some operation on the objects within the area.
setpoint
A special symbol used to specify initial node voltages during
simulation.
simulation
The use of a mathematical model to represent the physical operation of
a circuit design.
stimulus
Symbols placed on a schematic to identify digital and analog voltage
and signal sources used during simulation.
symbol
Consists of the graphical representation of a logical or physical
electronic part on the schematic. A symbol may have one or more
associated attributes.
symbol definition
Consists of the data from which the netlist is generated. A symbol or
part definition consists of the following: the part name and any aliases,
its attributes, primitive definition (also called the circuit definition),
and pin definitions.
symbolize
Creating a symbol to represent a schematic.
translator
(1) Another name for a netlister
(2)The process of reading a schematic created by another design
program and converting it to a PSpice Schematics file.
view
A mechanism for allowing hierarchical symbols to have more than one
underlying representation, for example, defining a flip-flop to have a
transistor view or a gate view.
viewpoint
A special symbol used to display bias point voltages and currents
during simulation.
voltage viewpoint
Displays the bias point voltage at a pin. Any pin on part or a port may
have a viewpoint attached.
wire
A graphical indication of a connection between pins, buses and other
wires.
