The "fast edges" of modern electronic devices cause a lot of signal integrity (SI) problems. It is more and more difficult to use components within their specifications. The SI problems result in unexpected behavior of the hardware, reset problems, download problems, latch-ups, software hang-ups caused by the hardware and, last but not least, very noisy boards not compliant to FCC (USA), CISPR (EU) or VCCI (Japan).
In this very practical course for electronic designers, board- and IC designers, the theory behind signal integrity is explained and illustrated, practical problems are modelled and simulated, solutions are discussed and simulated. During the hands-on sessions the course participants use software to analyse system parts with SI problems and the effect of measures.
The course concentrates on signal integrity on a printed circuit board (PCB) and around the interface between board and IC. It does not cover aspects as architectures for fast systems.

Signal integrity problems may arise at many levels: within an IC, at the package level, on a PCB, at the backplane of boards, at inter-system communication.
There are issues that hold at various levels. But practical reasons often cause different approaches at different levels. This course concentrates on signal integrity on the PCB and around the interface between IC and PCB and is therefore highly relevant both for a PCB designer and an IC designer. The examples applied during the course, however, stem from the PCB area.
There are problems on signal integrity (and power integrity) that manifest themselves on a PCB but that should have been resolved on an IC. In case an IC strongly radiates (EMC), there are additional costs at PCB-level such as with housing or a metal shield, possibly the required performance may even not be reached. To prevent these problems the PCB designer might choose a chip set from another supplier.
Furthermore, a relationship exists between the pinning of an IC and the number of layers of a PCB. For financial reasons there is a strong preference for e.g. a 4 layers above a 6 layers PCB (costs are rising sharply with the number of layers). However, this can make demands on the pinning. If these demands are not handled properly, a 6 layer PCB might be necessary because of SI reasons. An alternative is to select an IC from another supplier.
