Drawing Signals
Signal lines are drawn in either Point ( ) mode or Signal Drawing ( )
mode.
Interconnecting Signals
If you draw a signal line so that the end of the line makes contact with a
second signal line, then those two signals will be interconnected. Also, if
you place a new device so that one of its pins touches an existing signal
line, that pin will be connected to the signal. If both of the signals being
connected were named, then you will be prompted to choose the name of
the resulting signal. Whenever three or more line segments belonging to
the same signal meet at a given point, an intersection dot will be placed at
that point automatically.
NOTE: For efficiency, signals are only checked for connections at their endpoints
and only signals actively being edited are checked. It is possible to create
overlapping lines that do not connect by unusual combinations of editing
operations. This situation is usually visually apparent at the time the editing
is done, since the intersection dot will be missing and the entire signal will
not highlight when clicked on.
 See more information on connection-checking under the Paste
command in Chapter 12, Menu Reference.
Connecting Signals by Name
 See the section below on Name and Pin Number Operations for details
on how signals are connected by name.
