A Comprehensive Method for the Design of BGA, Connector and Via Breakouts for Layout?

In designing via breakouts for BGAs, connectors and freestanding via transitions, engineers may box themselves into a corner where layout is exceedingly difficult. Designers may also fall into the “mole hole” of endless optimization simulations that seem more like a game of “Whack-a-Mole” than a design methodology. This presentation will provide a simplified process that […]

Cascaded or End-to-End Interconnect Models: What Do We Give Up?

Reduced channel simulation times can be achieved by simulating PCBs and connectors separately then via cascading. However, this approach introduces impedance and crosstalk inaccuracies. This presentation demonstrates the differences through correlated simulation and measurement models. It then uses fields plots to devise mitigation strategies to maintain the increased simulation time while avoiding simulation inaccuracy.
