Abstract:
1. A system for analyzing simultaneous switching noise (SSN) of a device under test, comprising: a first soft processor embedded in a device under test that dynamically programs a plurality of I/O buffers in the device under test; a second soft processor in an integrated circuit that dynamically controls a plurality of multiplexers which connect the I/O buffers in the device under test to a sampling oscilloscope and which allow a selection of a victim I/O buffer; and an integrated characterization environment running on a computer, wherein the integrated characterization environment transmits a SSN pattern representing the selection of the victim I/O buffer and one or more aggressor I/O buffers to the first soft processor and corresponding commands to the second soft processor so that a SSN waveform at the victim I/O buffer is captured and quantified by the sampling oscilloscope.
