Hi all, I'm new here.
I have a question about using a plane as shield.
I did make an analog design, so I drawed a star-gnd. Now I also like to have a shielding om het board, connected to only one pin of the gnd-net, at the star, not to the full net. This for emc (and the looks). Is here anyone who knows if this is possible?

Hi Martijn,
If you have a ground in Multisim, where you want to connect the shielding, it is good for your schematic design.
In your PCB design, this is something you have to keep in mind.

Hi Bas,
Thanks for your answere.
I am sorry if I wasn't completely clear in my question.
I did use a ground in multisim, but the problem is that when I connect a plane to the ground it also covers/swallows the complete net. Due to the design I can't afford a plane that is connected to all the pins, so therfore I like to add a plane that is only connected to one pin, instead of a complete net.

Hi Martijn,
If multiple pins have the same net, they are connected.
Maybe you have to add an extra ground, that creates a new net.
