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?

    We actually use an extractor from another vendor.

    > and what is this 2.5-D solver ? Is it different from EM solvers.

    We use EMX to provide 3D simulations of the Virtuoso layout directly to determine the inductance and Q as a function of frequency. A model is fitted to the impedance which is substituted for the relevant area of the extracted view. The inductance/impedance of other traces neighboring the basic model are included in the extracted view.

    Information on EMX, if you need it, may be found at URL:

    I hope this helps understand out process.
