I did an extraction on a simple NOR gate with Diva.
But I've got following message:
"
saving rep transmitter/NOR/extracted"
However, when I open the 'extractd' view, it is empty.
Why it is empty?
Try to netlist the extracted view and check the netlist. Perhaps DIVA didn't really extract, and your view is actually empty.
Or: Check the extraction rules and find out, to which layers the extracted layers will be assigned. Perhaps you don't have these layers in your LSW, or perhaps they are not visible?
