Wiring with Bus and Joint elements
, placing the line just you need.
The bus, like a pipe, only transports signal lines, so it doesn't connect any
component.
To have a signal transported by a bus is necessary that a signal line ends (or starts, it's the
same!) on the bus. Every bus line must be identified by a name different from the
other signal lines carried by the bus.
|
The bus signal lines have a name, that must selected
with  , clicking over the track and entering its name
(attention to the already used names).
For example, in TUTOR1.SCH you can try to remove, with
To check new wirings, use |
| With  you can place a single signal port,
using the signal name you wish.
This kind of component is very useful to wire components far one from the other.
The option is also useful in case of file splitted schematics:
all the signal ports with the same name will be linked togheter, also if they exist on
different .SCH files, due to their definitions, stored in the netlist
of every schematic file.
When the netlists will be imported in the pcb file
all the signals with the same name will be wired togheter.
|
You can place many signal ports with the same name, so they will
be electrically wired togheter. Always use 
to check the
real electrical circuit connections.
| A signal line can be transported by a bus simply
placing an extemity of it over the bus. With  you can do the same thing, but in a very professional mode, using 45° bus ports.
These ports came with its silk name and must be connected with schematic signal lines to
other schematic elements. The signal port extremity, below the port name,
is wired to the user specified signal. You can verify this thing
with the command .
|
| There are another mode to link schematic circuit components to
pcb elements: using joint. These are schematic components
that the user can assigns at one specific pin of every pcb component.
These elements are very useful, for example in case of big pcb connector, that cannot
be drawn in a schematic file.
In fact, because pcb components have many different footprints, it's hard to draw for every pcb connector, its schematic equivalent shape. |
The joint is a schematic component, only maded by a single pad and, optionally, by some silk elements (the one I use is maded by a pad and a little external circle silk). To make a joint type component, for example in the COMP_SCH.LIB library file, follow the Lesson 5 steps to make a schematic component, using "Pattern" = JP, "Ref ID" = JP?-?. The other fields must be left blank.
| To use a joint place it with  .
In the "PCB Pattern" field insert the pcb component type that
must be wired to the joint, then wire the joint to a specific signal line.
In this example the pcb component is MOR2, a two pad connector.
The specific pcb component pin that will be wired to the joint must be indicated
in the "Ref ID" field, after the joint group number, with a minus sign followed
by the pcb component pin number.
|
In the image above you can see that the joints connected to the same pcb component have the same number, followed by the pcb component pin number. All the same group joints must be assigned to the same pcb component. To better understand how joints works, you can download the file PicProgr.zip (17 Kb .zip) that contains the PICPROG.SCH file, where I've token the example above.
