[IBIS-Users] Validation of IBIS 5.0 model with package parasitics

Hi all,

I am trying to validate an IBIS 5.0 model at 500Mbps with package parasitics (R, L, C for supply, ground and pad) and on-die RC decoupling. The issue is that the I-T waveforms are not matching when I add inductance to the ground terminal. When I remove the inductance on the ground terminal keeping the rest of the setup same, the I-T waveforms correlate. Has anyone come across this issue or any suggestions on rectifying the same?

Thanks & Regards,
Rinsha
