ABSTRACT:
Optical triggering system and method for synchronizing a test of an integrated circuit chip with its operation. An optical triggering system includes a testing mechanism, such as a PICA testing mechanism, for testing an integrated circuit chip. An optical trigger mechanism generates an optical trigger signal for synchronizing a test of the integrated circuit chip with its operation. The optical trigger mechanism provides an optical trigger signal having reduced jitter and a higher frequency rate than an electrical trigger signal resulting in a more accurate test of the integrated circuit chip.
