<h1><center>Creating a Library Device</center></h1>
<hr>
Creating a new component part in a library has three steps. You must
follow these steps as they build upon each other.
<p>
To start, open a library. Use the File menu Open or New command (not
the USE command).
<p>
<b>Create a Package</b>
<p>
Packages are the part of the device that are added to a board.
<p>
Click the Edit Package icon and edit a new package by typing its
name in the New field of the dialog box.
<p>
Set the proper distance <a href=48.htm>GRID</a>.
<p>
<a href=62.htm>NAME</a> and place <a href=67.htm>PAD</a>s properly.
<p>
Add texts >NAME and >VALUE with the <a href=93.htm>TEXT</a> command (show actual name and
value in the board) and draw package outlines (<a href=100.htm>WIRE</a> command) in the
proper layers.
<p>
<b>Create a Symbol</b>
<p>
Symbols are the part of the device that are added to a schematic.
<p>
Click the Edit Symbol icon and edit a new symbol by typing its
name in the New field of the dialog box.
<p>
Place and name pins with the commands <a href=69.htm>PIN</a> and <a href=62.htm>NAME</a> and provide pin
parameters (<a href=32.htm>CHANGE</a>).
<p>
Add texts >NAME and >VALUE with the <a href=93.htm>TEXT</a> command (show actual name and
value in the schematic) and draw symbol outlines (<a href=100.htm>WIRE</a> command) in the
proper layers.
<p>
<b>Create the Device</b>
<p>
Devices are the "master" part of a component and use both a package
and one or more symbols.
<p>
Click the Edit Device icon and edit a new device by typing its
name in the New field of the dialog box.
<p>
Assign the package with the <a href=66.htm>PACKAGE</a> command.
<p>
Add the gate(s) with <a href=26.htm>ADD</a>, you can have as many gates as needed.
<p>
Use <a href=36.htm>CONNECT</a> to specify which of the packages pads are
connected to the pins of each gate.
<p>
Save the library and you can <a href=96.htm>USE</a> it from the schematic or board
editor.
