Abstract
A system for measuring a test voltage level (Vx) in a location within a chip is presented. The system includes an on-chip measurement device with an on-chip comparator and an on-chip storage. The on-chip comparator is configured for comparing the test voltage (Vx) to be measured to a reference voltage (Vref), while the on-chip storage is configured for storing the result of this comparison. The system also includes external (off-chip) equipment for generating the reference voltage (Vref), for generating probe signals for probing the state of the storage and for retrieving the state of said on-chip storage.
