A Holistic Power Integrity Approach Reduces Board Spins, Supports System Analysis and Reduces VRM Modeling Effort

Abstract: I hear many recurring complaints from engineers attending my lectures. They can be summarized as:
Continuously increased technology designs on a constant, short cycle.
Multilayer board spins are time consuming and expensive. Must be minimized.
Many key design parameters and guidelines are not provided by the semiconductor manufacturers or are inaccurate.
Power electronics engineers rarely get involved in the troubleshooting or modifications caused by their designs. This effort mostly falls on the high-speed engineers.
Far too many engineers are developing simulation models for free or inexpensive simulators. This costs valuable engineering time, without creating a net benefit to the system evaluation.
A simple design workflow could address many of these issues, resulting in more cost-effective designs with fewer expensive board spins. The proposed workflow would also reduce the effort expended by semiconductor companies in developing simulation models. The result is a unified, end-to-end model, providing power rail noise, spectral content, EMI, dynamic transient response and power rail impedance all within a single model. This approach also allows the analog, power, digital, RF and µWave models to all be incorporated into a single system level simulation model.
