Is there like an inductor finder for the sky130 pdk? In Xschem or somewhere ?

There are no characterized inductor devices in sky130. The best you can do is to estimate the inductance with a field solver like FastHenry.

@Tim Edwards is there a tool to help me determine capacitor sizes? I have used proprietary PDKs before where you could enter cap value and it would calculate size for you

I think xschem has the capability to set up Tcl expressions to handle that, although I don't know if Stefan Schippers has tried reverse calculations for devices sizes from values. But magic does have that implemented; you can use magic to generate a MiM cap and then enter the value and it will compute the size for you (this only works with the "square capacitor" option selected---Otherwise it has no idea how to balance length and width).

@Koustubh @Tim Edwards xschem estimates capacitance from W and L dimensions. Currently it does not do the opposite (although this could be possible improvement for square caps). With 2/3 bisecting iterations you can set W and L that gives you the right capacitance. For MIM capacitors both area and perimeter components are considered for capacitance calculation.
