Abstract
A VSLI chip is implemented with registers which log permanent and intermittent errors occurring within the chip as sensed by concurrent error detection circuitry (CED). If a fatal error is detected (one which would destroy the reliability of chip operations), then the chip is immobilized into a hold mode (freeze). Interrupts are signalled to a cooperating maintenance controller which can pass the error information to an external computer for display and for locating a faulty area.
