Primitive Devices on the Schematic
The primitive devices provided in the primlogi.clf and primgate.clf librar-
ies can be used at any time as part of a schematic, whether or not the simu-
lator is installed. However, these libraries are not intended to match any
real logic families and do not have any part name or pin number informa-
tion associated with them.
 See Chapter 9, Primitive Devices, for more information on creating
and using primitive types.
Simulation Pseudo–Devices
The simulation pseudo–devices (for example, those in the primio.clf library)
are handled specially by the Schematic tool. In general, you cannot modify
the symbols, pin types, or other characteristics of these devices. In addition,
they are treated differently from normal device symbols in the following
ways:
 By default, these devices are flagged “omit from report,” meaning that
they will not appear in any netlist or bill of materials reports. This
setting can be changed using the Schematic tool’s Get Info command.
 These symbols will not be assigned names when placed on a
schematic. Names can be manually assigned, if desired.
The Switch and Keyboard types respond to a normal mouse click by chang-
ing state, rather than being selected. To select one of these devices, hold the
key pressed while clicking on it.
