Introduction Until now, verifying that timing in 33 MHz 64-bit PCI designs met the setup and hold specification, required either very tedious meas- urements of all signals with a digi- tal storage oscilloscope (DSO) or a very high speed logic analyzer, which is very costly. The timing check feature of the E2920 PCI Series Exerciser/Analyzer simulta- neously monitors all 87 synchronous bused PCI signals for both setup and hold timing violations and identifies suspect individual signals. It works with your DSO to speed up the timing verification process not only by quickly telling you which signals are violating timing, but also triggering your scope when a timing violation occurs.
