Connectors and Discretes 43
IMPORTANT: The signal attached to a signal connector device is actually named to match the pin
name of the signal connector pin specified in device symbol editor, not the type
name. In most of the power and ground symbols provided with LogicWorks, these
two names are the same. However, it is possible to create a symbol called
“Ground” (for example) in a library that actually names the attached signal
“GND”. The Ground symbol in the spice.cct library is an example of this—it
names the attached signal “0” to match the SPICE ground–naming convention.
 See Chapter 11, Device Symbol Editing, for more detailed information
on this procedure.
Connectors and Discretes
In LogicWorks, each symbol is considered to be a separate device and each
device is normally assumed to be one IC package with a standard pin num-
bering scheme. Thus connectors and discrete components will require spe-
cial consideration.
Handling Connectors
Connectors can be handled in one of two ways:
 A special symbol can be created for the connector with the appropriate
number of pins and pin numbering specified for each pin. This can be
done using the device symbol editor to create a device symbol using
your own picture.
 Each connector pin can be created as a separate single–pin device or as
a custom symbol. The second option is preferable only if you need to
spread the connector pins over different parts of the diagram. In this
case, each “device” must be given the name of the connector and the
pin number associated with that pin. The report generator will normally
merge all devices with the same name into a single component entry.
Following is an example of these two methods:
