I need additional information on the IC characteristics in order to run accurate power integrity simulations in Hyperlynx. The IBIS model supplied does not take package characteristics into account. In addition to this, there is the internal regulator (I am running off a 3.3V rail) I would like to know if there is any internal capacitance which may aid power integrity. Is there a model for the part I could use or additional guidelines for power integrity I could follow?
The decoupling network on the evaluation board is what I have used as a reference but this does not provide enough margin in my design at higher frequencies.
