[IBIS-Users] IBIS ver5.0 [composite current] and [ISSO PU/PD]

Dear all,
As I know, for solving the SSN problem, IBIS version 5.0 adds section
[composite current] and [ISSO PU/PD]. Then I have some questions:
1. How will the simulator work with the [composite current]? Does it
directly adopt the power terminal current value at the [composite current]
when the input voltage over the threshold voltage? But I feel different
rise/fall time will lead to different current value at the power terminal.

2. The section [ISSO PU/PD] is likely to provide a gate modulation
coefficent on the original output current. In specification, the
Ipu=Kpu(t)*Ipu(Vcc-Vout(t))*Ksso_pu(Vtable_pu) and
Ipd=Kpd(t)*Ipd(Vout(t))*Ksso_pd(Vtabke_pd). so does it mean the total output
current is Ipu+Ipd? how does the simulator decide the value of Kpu(t) and
Kpd(t) according to the data in IBIS file?

Thanks and regards,

Yuancheng
