[Xcircuit-dev] XSPICE output possible?

First off, I LOVE this program. I use it for just about everything I can
because of the seamless transition from design / simulation to publication
quality figure insertion.

I'm just curious about something. I can currently generate fully functional
SPICE netlists and have built up quite a robust library of sources and parts
from various vendors with only minor PSPICE corrections. However, I am
currently trying to use XCircuit to do some mixed-signal modeling and am
having a difficult time generating the proper XSPICE syntax from the 'spice'
line.

For instance, I have the following information on my example inverter
symbol:

Standard SPICE:

XCircuit Output from Symbol -
spice:xinv%i %pin %pout my_inverter
spice:.model my_inverter inv(blah blah blah)

SPICE netlist -
xinv1 input output my_inverter
.model my_inverter inv(blah blah blah)

For XSPICE, I have to deal with behavioral nodes which are vectorized [nodes
must be in brackets] as shown below:

XSPICE netlist -
ainv1 [logic_input] [logic_output] xspice_inverter
.model xspice_inverter inv1(blah blah blah)

I have tried every possible permutation imaginable on the %p pin designation
to get the brackets included in the output. If this is possible, I would be
very thankful if someone would show me how.

Thanks in advance,
M. Jackson
