CDL Import 5-terminal MOS transistor (deep nwell)

Hello,

I am trying to import a CDL netlist using spiceIn (both command line and through CIW).

My problem is that the netlist includes a deep-nwell NMOS transistor (model nrf_dnw) and this transistor has 5 terminals.

When running spiceIn, I get the error below:

- - -

Instance: M61
Instance has master: 'mos' model/subtype: 'vss'

Master Cell: 'mos'.
Did not find 'silterraC18G.mos:symbol'.
ERROR (SPICEIN-24): Spice In did not find the symbol view of the master cell 'mos' of the instance
'M61' in the subcircuit 'afe_rf5'. Specify the reference library that has the symbol
view of the master cell, or use device-mapping to map 'mos' to a different
cell.

The line in the cdl netlist that generates this error is:

M61 net11 net4 vss vss net12 nrf_dnw w=1e-05 l=1.8e-07 m=1 finger=1

My device map file includes the following device:

devSelect := nfet nrf_dnw
propMatch := subtype nrf_dnw
propMap := w w l l m m finger finger
addProp := model nrf_dnw

I can successfully import CDL netlists with "normal" NMOS transistors (4 terminals).

I am using Virtuoso IC6.1.6-64b.500.11.

My questions are:

1) Is it possible to use spiceIn to import this 5-terminal NMOS transistor?

2) If yes, what settings should I use?

Thanks and best regards,
