Overview
The learning process is achieved through clips, connectors and probes that are attached to clusters of components. System 8 Ultimate guides the operator to place and walk the clips around the reference circuit. System 8 Ultimate generates the most efficient sequence of clip combinations and movements to learn all possible connections. However, the operator can modify and override the automatic placement of the clips if necessary.
To minimise operator errors, the system applies an orientation check and pin check to confirm clip contact and position. RevEng learns without applying power to the board and limits the applied voltage and current so that semiconductor gates are not affected - it is also safe to use on low power technologies. There is a wide range of IC clips and connectors. If a clip or connector is not available or cannot be fitted due to the physical constraints of the board then the hand held probe and buzzer facilities are used.
