Help!on spiral inductor modeling!

tjjbraye
Hi every buddy,

I'm using VPCM from MMSIM61 in IC610 platform for modeling  spiral inductor .After generating cell,I could only open layout view.But I can't open any other view such as symbol,schematic.In the CIW prompt window,it gives the following warning:
*WARNING* dbOpenCellViewByType: Design database revision (59) is not compatible with current revision (99).

So what 's wrong with me?
My component type is differential inductor and shape is octagonal with 2 ports.
Accuracy selection:Full-Wave EM Solver.
Please,anybody can help mee!
Thank you in advance!

  •  Maybe it is related to the database format? I'm not sure if MMSIM61/VPCD will save to OA format, since it is quite old maybe it still uses CDBA. Have you tried a newer version of MMSIM? Or an older version of IC? I use IC5141 and MMSIM62 and I have no problems with the cells generated by VPCD.
