Creating Multiple Parts in a Single Device

Former Member

Hi,

I would like to understand how to create multiple parts for a single device.  Exactly like the rcl.lbr is configured.  In the rcl.lbr, when I select C-US, there are multiple devices all with it own package.

 

How do I re-create this in my own library?  I want to make multiple parts for a single device, like resistors.

 

If someone can point me in the right direction or tutorial that would be great.

 

Thanks,

Mike

    What you're looking for is multiple packages for a single device.

    Recall that a device associates one or more//_symbols_ with one or more

    packages.  Examining the device editor screen, the top left pane

    contains the schematic symbols.  The bottom left pane contains a

    description of the device.  The bottom right pane contains all the

    variants of the device, each variant being a separate package.

     

    In the bottom right panel, click on "New", choose a package, and give it

    a variant name.  Then click on "Connect" to connect the pins on the

    symbol to the pads on the package.  If you haven't already, give the

    device a Prefix character or string - each time a device is added to a

    schematic, Eagle will append a 1, 2, 3, ... to the prefix.

     

    I believe the key that may have been overlooked is giving each package a

    different variant name.  For simple devices, like R's and C's, I provide

    a name of "-0603", or "-0805", just so that the package shows up in the

    schematic.  For more complicated parts, like microprocessors, I set the

    variant name to the suffix from the part's datasheet designating the

    package.  For instance, 'N' for DIP packages.  In the schematic, the

    device appears as the device's name concatenated with the variant name.

     

    For more information, refer to the Eagle User Manual in Chapter 4.4.  In

    the English version of 6.5, start at the bottom of page 79.  I would

    also read Chapter 18 in the Tutorial, in particular starting at the

    bottom of page 63 in the English version of 6.5,
