Print Verilog-A subcircuit value using HSPICE
May 01^st, 2015, 6:27pm

Hi everybody,

I'm using verilog-A to describe a subcircuit which I implement in a HSPICE netlist.

The subcircuit comprises a set of functions that are interdependent. for example:

F1 = V(a,b)*C1
F2 = F1*C2*V(a,b)
F4 = pow(F2,2)*exp(F1/C3)
...
I(a,b) <+ F4 //voltage dependent current source

When I run HSPICE I would like to PRINT several functions of the subcircuit.

What would be the proper command in order to do so?
(I'm running a transient analysis in HSPICE)

something like:
.PRINT TRAN X1.....

Thanks for the input!

cheers,
JS

Otherwise, you could use $strobe within the Verilog-A module to print; I think that comes out in the standard output from the simulator.

Rather than real F1, F2, F4; you declare them with (* desc="op-pt" *) real F1, F2, F4; Then you should be able to print them the same way you would print GM for a transistor. .print dc x1:F1
