Inductor value and its Q factor

engrvip

How can I measure value of an inductor and its Q value from its layout in virtuoso.


And how will that inductor be calculated ? will it be using some EM solver ? or will it be a parasitic extraction?

    In our organization, we use the extracted view of the layout to simulate inductor Q using both spectre and a 2 1/2 D solver. The extracted view includes inductive components of the desired inductor as well as any neighboring paths. It is often necessary to include other parts of the circuit confusing the inductor in case they contain traces whose inductance is significant.
