Parasitic extraction problem

PS90

I have made a CMOS based circuit and then developed its layout. The DRC, ERC etc. all shows no error. For parasitic extraction, i have used QRC. Still, no error shows and extraction completed successfully. But, when i see av_extracted view, only parasitics and pins are shown but no layout, because of that i am unable to do post-layout simulations. I am unable to understand this rather strange problem. So, i have attached some images of av_extracted and layout view alongwith the DRC and QRC setting on my setup. Please help in this matter.

    Hi Pushkar Srivastava

    I think you had not provided any info on whether there are actual non-parasitic devices in the extracted view. Would you please try the following?

    a. Open up the extracted view
    b. Go to "Launch->ADE L"
    c. Go to "ADE: Simulation->Netlist->Create"

    Do you see any mos devices in the generated netlist?

    Best regards
