Searching Nets

[SS]

If use dbFindNetName to find a net I can find it on the design. The
skill interpreter returns the netId

However, there are no figs associated with the net. netId~>figs
returned 'nil'

Also , I cannot find the netname using the Edit->Search

What could be wrong here ?

Hi Sriram,

It's quite possible to have nets in the database without any physical
representation. For example, this will happen if you're using Virtuoso Layout
XL, and you have not connected up the wires for the net. The connectivity is in
the database, but it's not been physically implemented yet.

The same thing can happen if you use things like VerilogIN or CDL IN and produce
a "netlist" view - this contains instances, terminals, and nets, but no wires
and pins - so there's no graphics.

You didn't say what kind of data you were looking at, so the above is just a
general comment...

Regards,

Andrew.
