I want to create a single line model, multi line model and/or IBIS model of an interconnect for simulation in Hyperlynx software but can't understand how to do it when the manufacturer has given no related parameters whatsoever. The interconnect is this one:
It's a connector: -
And therefore a very basic component. You should be able to easily estimate inter-pin capacitance from dimensions. Ditto pin inductances and depending on the plating material you should be able to calculate resistances.
But, it's only worth doing if you are sending signals through the pins greater than about 50 MHz.
Alternatively ask Samtec - they are normally fairly amenable to questions like this. This document looks like it contains some information that will be useful.
