Course Overview

This workshop is aimed at developers who want to implement high-speed interfaces between semiconductor components and who want to design complex high-speed circuits at board level. This Workshop is designed for developers who not only design schematics but also systems and the layout.
You will learn to judge when signal integrity is important and relevant, to interpret, for example, IBIS models, and to select appropriate termination procedures. Signal refection and crosstalk effects are described and demonstrated by simulation. Simulation examples are for typical PCB structures. You will learn how to implement high-speed buses, including clock design, loading and signal termination. Furthermore, the power distribution and bypassing design are main topics.
Detailed discussion of solving potential Signal Integrity problems on high-speed memory interfaces and serial transceiver links (optional modules).
