After you've placed the components and the power points it's necessary to
connect them togheter with the ![]() The graphical lines can be placed everywhere, because they are placed into the Symbol layer, that during the automatic creation of the TUTOR.NET file, containing the wirings list, are not considered. So, if you connect the components with a graphical line... is the same that you do not connect them! The wiring of the electrical elements must be done placing the extremity of the signal line exactly over the pin of the component to connect. The line can have every type of shape and be maked by many segments joined toghether... but the only important thing is that the extremity will to coincide with the master pad (green enhanced into the figure above) of the components. Every component have at least one master pad, that represents the effective and real electric connection with the external world. |
In the electric scheme of TUTOR1.SCH doesn't exists crossed signal lines, like
it happens in many electric schemes. To understand if a couple (or more) crossed signal are
wired toghether, Circad distinguishes between crossing (example C) and
wiring (examples A, B, D, E).
In the A example a signal line extremity ends over the route of another line.
Circad will make
these lines electrical wired togheter. In these case it is a good method
to place a Signal Dot with the When a line simply cross another one without the user press the left
mouse button onto the cross point (red enhanced) durind the wire placing, then
Circad will consider the lines electrically indipendent (example C).
If the user press the left button mouse onto the cross point, the program will
electrically connect the lines. To clarify if a couple of signal is joined or simply
crossed is always a good thing to use a Signal Dot, with the

To verify the signal lines were placed correctly, you can use the
command, pressing the left mouse button over a track line.
Circad will enhances in white all the signal lines connected - phisically, by bus,
by power points, etcetera - allowing to verify the wirings are correct. To
remove the enhancing simply click far from the signal lines.
To automatically verify the wirings were done correctly you can also use the
or
commands, that controls the tracks
placed next (+) or previously (-) respect the last signal line checked with the
command. If you have never used this command all the tracks in the
circuit will be checked.
These commands are able to verify the presence of short-circuit between named
signal lines, like +VCC and GND, with a "Two or more Signals are
cross-linked" warning message. In the next lessons you will learn how to manage
correctly the name of the signal lines.

After you've placed all the signal lines, you'll can appreciate one of the most powerful
function of Circad, that is the ability to move, rotate or redimension a
component and to drag, at the same time, the wired signal lines.
