Hello,

I trying to design and simulate cmos Op-amp.

I have done DRC,LVS and QRC without any error here is a screenshot:

DRC:

Note: there are some warnings however my professor asked us to ignore
these errors.

LVS:

and

QRC:

ERROR (OSSHNL-116): Unable to descend into any of the views defined in
the view list, 'spectre av_extracted', for the
instance 'avD24_1' in cell 'op-amp'. Either add one of these views to
the library 'PRIMLIB',
cell 'nfetdiode' or modify the view list to contain an existing view.

End netlisting Jan 24 15:11:01 2012

ERROR (OSSHNL-514): Netlisting failed due to errors reported before.
Netlist may be corrupt or may not be produced at all. Fix reported
errors and netlist again.
....unsuccessful.

Is that a problem with the schematic or layout that I need to modify.

Regards

Zubair.
