[IBIS-Users] LVDS RECEIVER Validation

Hello Guys,

   I'm confused while running LVDS Receiver IBIS validation. This
receiver is internally terminated with 100 ohm between non-inverting &
inverting pin. In its IBIS model I have instantiated a [R Series] Model
for this resistor. But when run Hspice simulation, I don't get expected
results. I doubt it is because I'm not calling resistor model in deck
file but calling only Model for inverting & non-inverting pins. 

I don't know to call resistor model in deck file. is there anyway to
call resistor model? Actually I was reading some doc and fount that
Resistor [R Series] model is not supported by some simulator and user
has to put same resistance in deck file manually between those two pins.
I'm not sure if this is true for Hspice also. But when I did so I got
better and expected results.

 

Can someone put some lights on it, what I'm doing is correct or not?

Thanks for your time.. 

 

Thanks & Regds,
