Hi guys.

I am new here and I am a newbie with respect this topic, of modelling inductors. I'd like to know if there is someone here that have a tutorial where describes how to model an inductor just to have somewhere to start and explore.

Kind regards.

Thank you so much for your reply Frank.

In fact, I have heard about sonnet and I've already downloaded it but not tried. I'll install the software and explore a little bit. During my search in this forum I found some threads where there were explained the difference between several types of software that do simulations (3D, 2.5D (like momentum) and so on). Regardless the fact that I am a newbie on this field (modelling inductors), sonnet is a Full EM simulator?

I want to design an inductor for my design (in cadence, microelectronics) and I'd like to optimize the design of the inductor to get the best performance of my circuit and at same time to learn how to model inductors.

Kind regards.

Okay. Thank you. I am watching some of the Sonnet IMS Tutorials and I've already read the EM simulation software page from Wikipedia (http://en.wikipedia.org/wiki/EM_simulation_software).

From the list available from Wikipedia, the software that I have heard about were: HFSS, ADS Momentum, ASITIC, FastHenry (despite the fact that I have never used them) and now Sonnet (which I am enjoying watching the tutorials). From what we can observe from the Wikipedia descriptions there is something that came up in my mind: 1st - What is "Mesher"? Looking to the Mesher and the Algorithm column I wonder which one are the most precise/credible in the results?

Taking the advantage of this post, I would like to ask you, if you are some kind of Sonnet guru, one question regarding Sonnet Software.

While watching a tutorial on "RFIC Spiral Inductor Modeling" (which is from my interest), http://www.sonnetsoftware.com/resources/videos/IMS2012/rfic_spiral.html, I didn't understood something.

In minute 6:35 is presented the process stackup and in minute 7:38 how the import of GDSII will be done. In 8:56 the tutor describes in practice what is done. In minute 9:10 the tutor says that the file that he will select contains the stack up configuration from the technology (metal and via characteristics) which is already setup and he says "everything that we want when we create the file by hand in sonnet project", "which is an empty sonnet project".

With this my question is: We have to build that stack up our self? If so, it is only needed to build the corresponding layers that are from our interest (in this case, for example, metal 6 and metal 5)? And the final question how do we build this stack up empty project?

Kind regards.
