PROBLEM TO BE SOLVED: To enhance a photon discharge responding to a signal, and to enhance signal observability for circuit analysis. SOLUTION: A method and a device which enhance photon emission, responding to the signal in an integrated circuit 110, are indicated for the observability of a signal state using PICA. In an embodiment, photon emission is enhanced by adding a beacon 112 to an object signal, and a voltage is applied on the beacon 112. The photon emission can be discriminated for increasingly from noise, because the voltage is made higher than an operating circuit voltage Vdd so as to enhance the photon discharge, with respect to intensity and a energy. In many of the embodiments, the beacon 112 contains a transistor, and in several embodiments, the beacon 112 enables photon emission, from the beacon 112 and contains an enabling device for disabling this. PICA detector 130 captures photons and generates a time trace, after processing. COPYRIGHT: (C)2006,JPO&NCIPI
