[willb8]

Hello,

I'm making a design in which i've multiple ground s(AGND,DGND,PGND).

I've 4 layers. one is dedicated to the grounds(the third).

i want to divided this layer for the 4 grounds.

how do i realise it?

the second layer is dedicated to power signal.

How do i realise it(just the power net muss be routable here)

sorry for the question i'm a newbie.

thanks

Hi willb8,

when you use the Netlist Editor (Ultiboard->Tools->Netlist Editor) you have the ability to specify for every net seperately on wich layer in shall be routed. This is possible from the spreadsheet view too. I think this is it that you are searching for.
Additionally you can add "Net Bridges" to mechanically connect your different ground signals.

Hi,

Thanks oyster for the answer.

How kann i divide my ground plane, then i've 3 of them?

Do i realize this with "place-> copper Area"?

Do i need to flood a plane in Ultiboard?

Should my Ground me declare as a power plane? what's the difference?

thanks

Hi,

you can place copper areas and assign them to a specific net.

The power plane automatically fills everything that is possible with the desired net.
