Help with real number modeling of loads

[spigeld]

Hi,
I'm trying to verify a mixed signal design that characterizes a load than applies voltage to that load.
To characterize the load the circuit applies voltage to it than measures it's current.
And in the second phase forces current through it and measures it's voltage.
after taking into account these parameters voltage will be applied to that load.

The thing is that the stimuli to my design is a resistive load rather than some sort of voltage source and i'm not sure how to model such a thing.
i was thinking about pre calculating the voltage drop on the load and forcing it to the circuit but i'm not sure if that would be a good idea.

Any suggestions?

P.S
Has to be using Real numbers, can't use verilogA

Thanks

Are you talking about analog simulation or digital simulation dealing with digitized analog signals? Which tools?

a digital simulation with digitized analog signals
but i need to keep the interface identical to the analog module so that i could later on replace my model with the actual design
I'm using IES and MMSIM
