Resolving the Critical Link: Modeling and Simulation of Complex, High-Speed IC Packages

January 15, 2007, An-Yu Kuo - Optimal Corporation

As data rates achieve multi-Gigabit levels, interconnect plays a commanding role. Not only on signal transmission from ICs to boards through Packages, but also on power delivery from voltage regulation module on boards to ICs via the Package. Therefore, the Package now becomes a bottleneck on signal and power paths. Their behavior affects signal quality and the efficiency and stability of power supply. To optimize in performance and cost, Package structures have to be properly modeled, extracted and simulated with the rest of the circuit on signal and power delivery paths.Read more »
