LVS in virtuoso

hello aifi ..

Well if u can generate a schematic from the layout and then perform LVS .. never it will show any errors .. so the following are the steps

1) you make the layouts using candence vituso ..
2) you have to make a schematic view.
wen u start the icfb .. u can either make a new layout r new schematci .. wen u opne a new layout the tool bar will show varios metal layers ... subtrate and poly .. but wen u open a scgematic u have the options of chossing the gates r trasistors ..

so please follow soem tutorials where it shows from a small inverter ...

best of luck

you can extracte the layout and get a netlist, then , you can verify it with hspice .

LVS is a kind of Sanity check , to check for the equivalency between two abstraction levels.

Hi,

As the name specifies LVS - Layout versus Schematic, we need both Layout as well as schematic. With only layout if u run LVS its not worth.
