problem in import spice

Hi,

I need to generate schematic from cdl through IMPORT --> SPICE .

It is working fine for regular Vt devices but for lvt (low-Vt) devices showing error as

Instance: MM1

Instance has master: 'mos' model/subtype: 'lvtnfet'

Master Cell: 'mos'

Did not find '<reference_lib>.mos:symbol'.

ERROR (SPICEIN-24) Spice in did not find the symbol viewof the master cell "mos"  of the instance MM1.

not sure from where this "mos" master is taking. It is working fine for other devices.

Please help me in debug.

Thanks,

Machha.

    Hi Machha

    When spiceIn is unable to find a suitable user-defined mapping for a device, it tries searching for generic names such as "mos", "res", etc. You had most likely not included the appropriate reference library or device mapping.
