Guidelines for supporting successful simultaneous switching output behavior for chip-package-board systems.
This paper concerns guidelines to support successful SSO analysis for Chip-Package- Board systems. The procedures detailed address extraction and circuit simulation application of high node-count (N>100) frequency domain models. The focus of this paper is the low frequency portion, including DC, of the spectrum for broadband S- parameters. Frequency domain model extraction options and transient circuit simulation options were investigated and their interdependencies are discussed. These procedures apply to a broad class of extraction and transient circuit simulation tools typically applied to support SSO analysis. A high-speed digital board with 50 single-ended channels was applied as a test vehicle for guideline development.
