view with device, parameter and connectivity information plus parasitic
devices if desired, that it can be netlisted and simulated.
In the command rule file it's defined how much layers will be copied over
from the layout to the extracted view. Usually this are just the layers
which are used for the interconnects and they will have the layer purpose
'net'. This is enough to probe signals in the extracted view.
But this depends on your design kit and the people who are developing it.

thanks for your reply,Bernd.
when i extracted a capacitor , there is no layer left , but a parasitic capacitor symbol. that means the layout circuit was cut off in the place of capacitor.
and even more, i made the post simulation using the extracted circuit , the results were totally different to pre-layout simulation results.
