Non-invasive timing analysis of IBM G6 microprocessor L1 cache using backside time-resolved hot electron luminescence

Picosecond imaging circuit analysis (PICA) is recently demonstrated to be a practical measurement technique of internal timing of ICs. This paper describes application of PICA to analysis of individual MOSFET switching times in the L1 cache write control circuits of the S/390 G6 microprocessor chip.
