34. Design for compliance: Locate I/O drivers away from sources of high frequency and near the connectors they serve. Clock Clock Buffer I/O Driver Edge Connector
43. Design for compliance: software and firmware Design for robustness: - checkpoint routines and watchdog timers. - checksums, error detection/correction codes. - “sanity checks” of measured values. - poll status of ports, sensors, actuators. - read/write to digital ports to validate.
46. Pre-compliance testing: EMI probes proximity probe 50 cable to analyzer center conductor looped back to shield and soldered Proximity probes are useful in localizing: - reactive PC board areas and components - reactive signal, I/O and power cables - reactive enclosure gaps and openings - by pumping signal in, as immunity probe
47. Pre-compliance testing: EMI probes 50 cable to analyzer 39 pF capacitor on center conductor contact probe Contact probes are useful in finding: - reactive component pins - reactive PC board traces and planes - reactive I/O and connector pins - driven areas of enclosures
