I would like to ask a question for an IBIS specification. I am not sure if
I am sending this email to the right place, if not please advise where it
should be sent.
Hello, if I have an internal 100 Ohms termination in my receiver between P
and N.
How is the appropriate way to model that in IBIS.
Please advise off different alternatives.
Thanks.
This is what I tried, but it did not work, It says this
ERROR - Component 'XXXX': [Series Pin Mapping] Pin2 '17': model type cannot
be Series or Series_switch.
