摘要:
In order to measure IDDQ in a large integrated circuit, multiple IDDQ monitors sampling the current drawn by selected portions of the circuit are placed on the integrated circuit chip. The output of each IDDQ monitor is combined and supplied to one output port (207) when any of the IDDQ monitors detect current in excess of a predetermined threshold. The output of each IDDQ monitor is also stored in a memory (209) for subsequent readout at a second output port (211) for detection of particular portions drawing the excessive current.
