3. Signal integrity of electronic boards
Signal Integrity (SI) is defined as an engineering discipline whose objective is to guarantee that on the board designed :
signals are transmitted and received correctly with controlled propagation times;
the propagation of these signals does not interfere with other signals or with the signals themselves;
the amplitude (current, voltage) of the signals does not exceed the limits guaranteed by the component manufacturers.
With this in mind, SI's actions are aimed at :
eliminates unwanted signal reflections and minimizes losses;
reduction of crosstalk or coupling between signals ;
minimization of reference voltage instabilities....

Regulations
EMC is subject to European legislation through the EMC directive, which is integrated with the CE marking directive that regulates the introduction of products onto the European market. A board designed to be integrated into a product and which is not itself a product placed on the European market is not subject to the CE marking obligation, and therefore not strictly to the requirements of the EMC directive. It must, however,...
