Abstract
A system for monitoring internal states of an integrated circuit includes logic nodes, selection logic and a monitor unit. The logic nodes are disposed within the integrated circuit and the selection logic is coupled to monitor pins externally accessible on the integrated circuit. The selection logic retrieves internal states of select logic nodes based on signals applied via the monitor pins. The monitor unit reads the internal states of the select logic nodes via the monitor pins.
