How to access subckt parameters in sim results?

$

Is there some particular magic to access a subckt level parameter in the simulation results?  For example:

subckt mycell (OUT)

  parameters VDD=1.8

  V0 (OUT 0)  vsource type=dc dc=VDD

ends mycell

I0 (1 0) mycell

I1 (1 0) mycell VDD=1.5

How can I figure out the value of the VDD parameter either as a "mycell" default, or preferably as an I0 and I1 instance level value?  I see in subckts.info.subckts  that the parameter *names* are in the PSF file.

TYPE
"subckt" STRUCT(
"subckt_params" STRING *
"subckt_terminals" STRING *
"subckt_instances" STRING *
) PROP(
"key" "sub"
)

but I don't see the *values*.   I'm assuming step 1 is I need to figure out the appropriate save option in ADE to get the appropriate save options into spectre.  Then I need to figure out how to access in ADE/Ocean.
