Power and Ground Connections
LogicWorks uses a type of pseudo–device symbol called a “Signal Con-
nector Device” to maintain connectivity between like–named power and
ground symbols that are used on circuit diagrams.
As soon as a Ground symbol is placed on the diagram, the attached signal
will be named “Ground” (the name will initially be invisible). This will cause
it to be connected by name to any other signals that have Ground symbols or
are explicitly named “Ground”.
Connectivity can be checked at any time by double–clicking on any ground
or power line. This will highlight all other like–named lines on the dia-
gram.
IMPORTANT: Signal connectors do not cause a logical connection to be made between circuit
levels in nested subcircuits.
Using Signal Connector Devices
Signal Connector Devices are placed on the diagram just like any other
LogicWorks device. A set of standard power–supply symbols are included
with LogicWorks in the connectors or pseudo devices libraries.. If you con-
nect two different signal connector devices together, you will be prompted
to provide a name for the resulting signal.
Creating Signal Connectors in a Library
Signal Connector devices are special primitive “pseudo–devices” in Logic-
Works and can be created using the Set Primitive Type command in the
device symbol editor to select the SIGCONN primitive type.
