probing signals in veriloga

[DReynolds]

I have a large analog chip and I am trying to write a checker for
functional verification and I need to be able to see signals in
various parts of the hierarchy. In veriloga, how do I get the value of
I1/I2/I3/V(some_node)? I figure I need currents and variables as
well.

For voltages, I thought about adding pins to blocks and propogating
the signals that way, but there are too many of them and it doesn't
help with the currents or variables... I haven't found any reference
to doing this in the documentation either... did I miss it?

David,

You can use "saveahdlvars" (on the Outputs->Save All form in ADE) to save
internal variables in Verilog-A modules. Is that sufficient for your needs?
