label of supply symbols

autodeskguest

Hi all,

I wonder if there is a way to automatically label a supply symbol (i.e.

GND) to reflect the actual name of the net it is connected to.

 

In my schematic I have about ten isolated ground nets. I named each one

with different (and meaningful) names, like: GND_MCU, GND_AUDIO,

GND_UART, etc...

 

To improve the readability of the schematic I would like to place a

label close to each ground symbol to show the name of "its" net.

 

Right now I'm able to do so only using the LABEL command, attaching it

to the net. It works, but it would be much easier if the symbols can

show it by itself, using something like >NAME or >VALUE placeholders.

 

Thanks

Marco

  • Hi Marco,

     

    You can create library parts for all your alternative voltages that you

    require and then these will have the right name and automatically set the

    signal name of the signal they are connected to. Manually setting the net

    name to be different from what the symbol implies and adding net labels to

    show the right value runs the risk of missing something and ending up with

    things not connected where you expect.

     

    In the library manager, duplicate the GND device and rename it to for

    example GND_MCU and do the same with the GND symbol. Then open the GND_MCU

    symbol and change the pin name from GND to GND_MCU also. Finally, open the

    GND_MCU device, delete the GND symbol and add in the GND_MCU symbol. Now

    when you place this in your schematics it will work correctly and put the

    correct name on your nets.

     

    IMPORTANT Remember to rename the symbol pin. Failure to remember this

    will result in the original name being placed on the nets which you may not

    see until it's too late, so check, check and check again when you create

    alternative power supply symbols!

     

    Best Regards,

    Thanks for your answer.

    Yes, this could be a solution. The drawback is I will end up with a list

    of symbols some of them used only in one project...

    Yeah, I'm aware of this.

    Do you think it would possible to write an ulp to do all this stuff? It

    needs several actions and it's error prone if you have to make dozens of

    such a device...
