Different Net classses on GND?

autodeskguest

Example: I have a CPU and power suppy part on my schematic. The CPU is

connected to GND via GND symbol and gets assigned to my own defined net

class GND. The power supply is also connected to GND via GND symbol.

 

Here is the problem: I would like to have a net class with smaller width on

the CPU part GND (8 mil) and wider on the power supply (20 mil). However,

whenever they are connected together the apply to the same net class.

 

How do I split them to be connected to the same net but have different net

classes?

 

I have solved it temporary by having them separeted in different net GND and

GND_MAIN and then connected together with a resistor (0 ohm). Feels stupid

but I haven't understood how to separete them into different net classes in

any other way...

    That works, but now you have another part that has to be loaded, bought,

    stocked, etc.

     

    I use Eagle devices I call "shorts".  They have two pins and just connect

    them together.  For the symbol I make a line just a little wider than a

    normal schematic wire.  I have several flavors for connecting only on the

    top layer, bottom layer, all layers, etc.

     

    The shorts library and a bunch of other Eagle stuff is in my Eagle tools

    release that is available for free from
