Hi all,

I tried to run LVS, but I had found the following error messages:

psub_StampErrorMult

psub_StampErrorConnect

Can they be neglected or do we need to set some thing in LVS window (I use Assura) ?

In most of the chip design cases you have more than one ground
net connected to substrate e.g. you have a digital and an analog ground
on your chip. In reality these net might be connect over substrate,
but for Assura LVS these nets have different net names, so it's a kind
of a short over the substrate for the LVS.

Therefore most of the design kits come with a dummy layer to isolate
one part or more parts of the substrate for the LVS, have a look for it.

Or otherwise all your nets connected to substrate should have the same name.
