Accessing Sub-circuit Port Currents in SpecreS

[eefet3]

I am trying to access port currents of the sub-circuit I have created.
I can easily do it in Spectre by using the termMapping with the
following syntax

nil C ":1" B ":2" C ":3"

However, in this particular case I have to use SpectreS. The above
syntax does not work.

Any ideas?

Thank you in advance,
