Advanced SI calculates the entire signal path from driver to receiver — from DC to 56 GHz, with IBIS-AMI models — providing clarity on whether the interface complies before the board is built.

The challenge
The solution
HOW IT WORKS
Driver, package, via, trace, connector, and receiver. The margin is determined by the total sum, not by the weakest single link alone.
IBIS-AMI models from the component vendor make it possible to simulate the actual chip rather than a generic driver.
The frequency range covers the serial interfaces that are challenging to make compliant today.
VALUE
From structural models and channel analysis to eye diagrams and margins on high-speed interfaces.
An interface is a chain of links, and the entire chain must comply.
The result is only as accurate as the models describing the ends of the channel.
What needs to be presented is rarely a curve. It is a margin.
The analysis is only worthwhile if it can inform decisions in the design.
Advanced SI rarely stands alone.
Implementation
The fastest route to a reliable answer is the interconnect you are already concerned about. It also provides the best baseline for comparison if you have measured it.
Which models to request from the vendor, and which requirements the standard actually specifies. This is where most analyses run into issues, long before calculations begin.
You gain access to specialists who have run channel analyses in practice and can discuss any result that looks unexpected.

A brief conversation is usually enough to clarify whether Advanced SI is the right solution for your interfaces. No sales pitch. No pressure. Just a direct technical discussion about the connections that need to perform reliably.
FAQ
Typically IBIS-AMI models for the driver and receiver. Most suppliers of high-speed interfaces have them, but they need to be requested and do not always come automatically. We can help evaluate whether the model you have received is usable.
Often yes. If the interfaces are not the fastest and the margin is not tight, they cover the need well. Advanced SI becomes relevant when compliance must be documented, or when the margin is so narrow that guesswork is expensive.
Close enough to make decisions about stackup, routing, and connector selection, provided the models are correct. As with all simulation, the result depends entirely on the input data — and that is what a proper setup is all about.
That belongs in OptimizePI and SystemPI. Signal and power integrity are interconnected, and most teams analyzing high-speed channels eventually need to address both.
