Primer: Designer's Companion To Verifying Signal Integrity

This primer focuses on signal integrity, a key measurement issue affecting digital designs. The term "signal integrity" encompasses the analog factors that affect both the performance and the reliability of digital designs. As system speeds increase, signal integrity becomes a greater challenge: it is ever more difficult to maintain clean pulse edges, low noise and aberrations, and nominal amplitude and timing characteristics. A rigorous regime of signal integrity measurements can trace these problems to their root causes.
