There is a new tool 'Passive Component Modeler'
comes with the MMSIM 6.0 URS2 stream.
Have a look at
Code:<yourMMSIMInstallDir>/doc/VPCMug/VPCMug.pdf
I it can model a set of more complex inductors
like differential symmetrical and asymmetrical,
based on a Assura procfile and p2lvs file.
I have not tested it so far.
Try with:
Code: setenv CDS_VPCM_HOME <yourMMSIMInstallDir>/tools/vpcm
vpcm
