Several "ground" and "Vdd" connections i

[DoYouLinux]

Hi all,

I just forgot a thing to ask. In my layout, I have to "Gnd" connections for ground and two "Vdd" connections for a supply voltage. Actually, each of them will be independently connected to each pad, and then will be tied together to the supply and to the ground plane outside the chip (on a PCB). However, in my schematic, I have only one "Vdd" pin and one "Gnd" pin.

When I ran LVS, do I need to set any parameter (in Assura LVS) ?

Will the LVS report some error message ?

Thank you very much in advance,

DYLinux

I think there is no need to set any parameter u can directly ru...

No need for you to set any parameters in LVS...normally if you have a multiple ground lines then in layout you can separate them by adding a PSUB2 layer in one of the ground.
