Abstract:
A system for detecting defects within circuits, the system comprising:a power supply unit, said power supply unit configured to transmit supply current to a circuit coupled to said power supply unit; a current meter configured to receive and measure said supply current, said current meter further configured to transmit signals indicative of values measured from said supply current; and an analyzer interfaced with said current meter and configured to test a plurality of circuits, said analyzer storing a test value that is based on measured supply currents transmitted to another plurality of circuits, said analyzer further configured to automatically calculate a different threshold value for each of said circuits tested by said analyzer, said analyzer configured to calculate said different threshold value for said each respective circuit utilizing said test value and a value measured by said current meter as said power supply unit is transmitting supply current to said each respective circuit, said analyzer further configured to perform a comparison of said threshold value determined for said each respective circuit to one of said signals transmitted by said current meter, said one signal indicative of a value measured by said current meter as said power supply unit is transmitting supply current to said each respective circuit, said analyzer further configured to determine whether said each respective circuit is defective based on said comparison performed for said each respective circuit.
