Racing against the clock and faced with the increasing rise time of logic, most of today's high-speed electronic designers must be concerned with the signal integrity of their designs. Deftronics provides signal integrity analysis methodology training as well as on-site/off-site signal integrity analysis support to help you address these signal integrity issues.

In the past, many companies completed their high-speed electronic designs by employing a high-speed electronic expert to advise the layout designer on the routing of critical signals. If applied at all, signal integrity analysis tools were run against the resulting layout and any problems were solved interactively. This was a satisfactory, if expertise-intensive approach for many companies.

As system bus speeds exceed 100 MHz and edge rates drop below 0.5 ns, new methods must be adopted.

In such high-end designs, system buses can connect several CPUs and span several boards.high-speed electronic behaviors is no longer limited to a few critical signals and can often affect more than 50% of the signals on the board. Each major net/bus must be considered as an entity and a strategy developed for implementing the signals for each net/bus.

Transmission line behaviors has become so complex that simulation is essential to lift designer experience. Manufacturing tolerances (e.g. slow/fast devices or the allowable range of characteristic impedance) must be taken into account to ensure that the resulting design can function within specifications under all possible worst-case conditions.
Traditional post-layout analysis is no longer enough to guarantee design success. Designers must be able to evaluate alternative layout strategies before layout begins, taking into account allowable manufacturing tolerances. As a strategy for each net/bus is developed, rules are defined for a layout that ensures that the net/bus will work under real world conditions.
By using high-speed electronic design and analysis tools early in the design cycle, system designers can eliminate layout iterations and ensure that products are marketed on time.
