40 Chapter 3—Advanced Schematic Editing
Note that the “..” format implies that bussed signal names cannot
contain periods.
The signals specified will always appear in the order given in this list
from top to bottom in standard orientation. Specifying numbered
signals from lowest numbered to highest is a good practice, as in the
first example above, since this matches the standard library symbols.
There is no fixed limit on the number of signals in a bus, but it is a
good practice to divide busses up by function (that is, address, data,
control, etc.) for ease of editing.
Any combination of randomly–named signals can be included in the
list, as in the following examples:
D0..15 AS
*
UDS
*
LDS
*
CLK FC0..3 MEMOP BRQ0..2
Once the list has been entered, click on the OK button or press the
key. A flickering image of the breakout will now follow your mouse move-
ments and can be placed and connected just like any other type of device.
Editing Breakout Pins
The signal name notation that appears on a breakout pin is actually a pin
attribute. It can therefore be edited by the usual attribute editing mecha-
nisms—that is, either:
Select the pin and choose the Get Info command in the Schematic
menu, then click the Attributes button;
or:
Click the text cursor directly in the text on the schematic, as illustrated:

Type the desired new name.
