How to make an ideal diode model for diode from analogLib?

I am trying to make a model and use it for ideal diode from analogLib library. However, I don't know how to modify the built-in potential (or forward voltage) of the diode. I tried to add VJ variable and set it to a small value like 0.1V. However, from I-V characteristic of simulation, it doesn't seem to have any effect on forward voltage at all. The built-in potential from the simulation is about 650mV.

Can anybody tell me how to do that? I want the diode is like ideal (zero forward voltage and infinite slope).

Here is the model file I used (diode.scs):

simulator lang=spice

.model schottky D (LEVEL = 3 IS=1p RS=0 BV=40.0 IBV=1p VJ=0.1 CJO=0 M=0.5 N=1 TT=0 )

Thanks a lot. It works. I want to study to write model and how to use it effectively in the tool. Could you suggest what I should study in order? For example, first study verilogA then...
