Schematic and Pseudo–Device Primitive Types
A small number of primitive types are used to distinguish the types of sym-
bols used strictly for schematic diagramming purposes. These symbol
types have no inherent simulation properties.
IMPORTANT: The pseudo–device types have specific pin order requirements that must be
followed if you create one of these symbols using the DevEditor tool. Refer to
Appendix A, Primitive Device Pin Summary, for more information.
Primitive Type Description
SUBCIRCUIT Symbol having an optional internal circuit. This is the
default for symbols created using the DevEditor tool.
SYMBOL Symbol with no internal circuit.
BREAKOUT Splits signals out of or into a bus. These symbols are
normally created using the New Breakout command
in the Schematic menu, although they can be created
using the DevEditor for special purposes.
SIGNAL CONNECTOR Used for power and ground connections.
PORT CONNECTOR Makes a connection between the signal to which it is
connected and a like–named pin on the parent device.
