ASITIC Layout

Hi Guys:

How reliable is ASITIC in modelling and generating spiral inductor layout?. Thanks in advance.

Re: ASITIC Layout

I think it is quite accurate, although I haven't compared its results with other simulators like HFSS etc.
 

ASITIC Layout

in my experiment . this is quickly tools . not accuate . the ADS moment is better nad accurate .
 

Re: ASITIC Layout

Any comments on toos such as SONNET. Thanks in advance

Re: ASITIC Layout

You can get good results, but you must be very carefully creating the technology file. This applies to any of these tools
 

Re: ASITIC Layout

you need to modify the parameter in tiny technology file to make sure it fits
the real sitiuation. You can have an experiment to simualte the inductor pattern
provided by froundy such as tsmc. Check the Fsr, Q and inductance, it should
be quite satisfied, especially in inductance value. But, somehow you may need to modify the parameter to get more accurate result.
 

Re: ASITIC Layout

ususally you use asitic as a first order estimate of your inductor design.

however with complicated substrates and package designs and with an increasing amount of inductors on chip you must do electromagnetic simulation with HFSS, Momentum or something similar.

use asitic for sizing and a first pass at the design.
