Zooming the Symbol Editor Window
The Reduce/Enlarge/Normal Size commands in the View menu allow you to
adjust the scale at which an object is viewed. The default setting for the device
symbol editor is to display objects at the same size as they will appear in the
schematic at Normal Size.
There is also a Magnifying Glass tool in the toolbar which allows you to
select an area of the symbol to zoom in on.
Adding Sequential Pin Names
The basic procedure for adding pins to a symbol is described in “Step 2—Add-
ing Pins to the Symbol” on page 143. However, the basic procedure requires
that the pin name and number be entered manually for each pin, which can be
rather tedious for large numbers of sequentially numbered pins. To solve this
problem, the Add Pins command allows you to enter a sequence of names in a
format similar to that used for bus breakout creation and for the Auto Create
Symbol command. These pins are added to the pin list, but not placed on the
symbol. After the pins have been added to the pin list, you can place the pins
sequentially on the graphic with no further typing required.
TIP: You can use the Auto Create Symbol command to specify the pin
names and auto-generate a rectangular symbol in one operation. See
“Automatically Creating Symbols” on page 169 for more information.
