Models make the difference in high-speed pc-board design

Simulation quality is only as good as the quality of the models being simulated. Knowing the types of component and board-interconnect models available from chip- and board-level-simulator, vendors can help make the design work the first time around. To meet shrinking design-time constraints and raise confidence in the final product, designers are increasing their reliance on virtual prototypes. An accurate virtual prototype requires accurate models of the system's components and of the interconnect between components. For designs based on virtual-prototype results, the phrase `garbage in, garbage out' can mean you have poor models and a system that fails to meet specifications.
