[IBIS-Users] Question on differential receiver IBIS modeling

From: Gowtham M <g-m_at_.....>

Hello IBIS experts,

I have a differential receiver with internal termination circuitry. The 
termination circuitry contains resistive elements along with some active 
devices. The model that I generated does not correlate well with the netlist, 
the currents do not match for 0 < Vin < 2*Vcc. However, -Vcc < Vin < 0 showed 
better match.

Could you please provide some hints/documents and guide me?

My understanding is that I should use the [Series Current] keyword to model the 
differential nature (for 0 < Vin < Vcc). Am I correct here? Could you please 
also guide me if/how I should take care of double counting of currents in this case.

Also, is there a search-able database of ibis-users mailing list archive? I 
believe this would really help me.

Thanks a lot for your help.

Gowtham
