Working with WREAL inout ports

jdimov

Hi,

I am trying to model a low pass filter in a charge-pump PLL and I'm trying to make that model a wreal model.
The issue that I'm facing is that my input is current driven, my output is a voltage, and all that is actually designed with an INOUT port.
Assuming that I can't change the port type or split the port into one that's input and other that is output - is there a way to actually define an inout port that would operate with two different types of values?

Is it possible to define custom discipline named (for example) ivreal and a connect module that would somehow describe both current and voltage of that ivreal port ? (for clearance sake, I am just familiar with verilog, verilog a/ms, still a novice... )

    Ok thinking things through here and reading my opening post, I think I sprouted some nonsense in here...

    But I'd love if someone could confirm this to me:
    from a programmer's point of view what I suggested was:
    ...
    inout vctrl;
    real vctrl_r;
    always @ some trigger begin
    something happens and vctrl_r = something new;
    end
    assign vctrl = vctrl_r;
    ...

    Thinking about connect modules and somehow differentiating currents and voltages of the same inout vctrl seemed possible at some point, but it ain't logical ... right?
