Coil inductor value goal in OPTFEKO

Hello,

I need to designed a coil at a specific inductor value (2.5 uH) over a certain frequency range (between 60 MHz and 100 MHz). Since the SRF of a planar coil is the main source of problem, I would like to use OPTFEKO to get the best coil with my fabrication process constraints (especially traces spacing).

In POSTFEKO, I see in the .out file that the inductor is shown. Maybe we can use this information to set a goal for OPTFEKO ? Or goal can only use imaginary part of the impedance to search the best parameters.

To summarize : I need to create a planar circular coil with a specific inductor value over a known frequency range, and I would like to use OPTFEKO for that, but I don't understand how to achieve that with masks, goals and everything ? (the coil's simulation is in the air, so it's an ideal case)

Can you help me ?

Best regards
