 Hello !
In sigxp, I faced a certain problem of simulation LVDS.
The Driver is TS201S(Analogh Device DSP) and Receiver is same device.
When I tried to analize the LVDS, I found some problem.
The problem is Overshoot which is not linear relative to trace length.


l
>> Driver ========================100ohm===========Receiver
l = 200mm => Overshoot : 670mV
l = 220mm => Overshoot : 532mV
l = 300mm => Overshoot : 530mV
l = 400mm => Overshoot : 632mV

Please let me know why this happened.
