Split VDD into VDDA and VDDD (analog and digital)

[buddel_2380]

I have the voltage supply VDD and would like to split it into VDDA and VDDD (separate voltage supply analog and digital). How do I do this with the schematic editor?

You can use the Add Symbol functionality and search for VDDA to add this power net. VDD is also an option (but not VDDD; you would have to copy and modify the existing VDD symbol to make your own VDDD).

The simple way is to split them using a ferrite bead (or two). Note the different ground symbols, as the ground plane splits via a net-tie:

Which is also something you can do locally at say a micro that needs a cleaner analog power (this is just using local digital ground):

Though I generally have differing voltages for digital and analog, so just use two ldos:

Thanks for your answer. I will try it.
