Your question is not very detailed. Any verification tool that can do LVS (diva, assura, calibre,
.....) must include device and connectivity extraction from layout in order to compare with a
netlist. For example, you may use assura to generate a netlist from a layout, provided you have
ruledecks for your particular technology.

Virtuoso-XL also has some (more rudimentary) connectivity extraction capabilities resembling that of
a schematic editor. One may certainly use it to extract a schematic out of a layout.

Hi Stephane
Thanks for your reply.Basically i was checking
only whether an nwell is connected to vss*. Is this possible through
SKILL or we need diva.

Sajin, as was previously mentioned, if you use virtuoso XL and have
connectivity information, then you can certainly find nwell connected
to vss without diva.
