Delete the schematic, there must be no schematic in this cell.
done. please see the pic below. my new layout name is "1".

Define missing cell parameters and make the inductor use them.
done. please see the picture below.

Use a separate cell for your schematic testbench.
also done. please refer to the pic below.
but unfortunately, my optimizer still not able to change the parameters!

if you able to optimize the spiral layout in the file that i sent you, please let me know. im still not able to do it

dr volker,
i didnt define Ri in the cell parameter above. i have redone the simulation after defining the Ri. However, my optimizer says "no improvement possible" in the 1st Iteration/Trial as usual! so no difference is detected by adding Ri.

i dont understand why "mil" is defined as e-06 here! Is this the rootcause?
