Latest Patents

One of his latest patents is titled "Analysis of Electro-Optic Waveforms." This invention utilizes an optic probe to measure signals from a device under test. The optic probe is strategically positioned at a target probe location within a cell of the device, which includes a target net to be measured alongside several non-target nets. A test pattern is applied to the cell, and a laser probe (LP) waveform is obtained in response. The target net waveform is extracted from the LP waveform through a series of steps, including simulating a combinational logic analysis (CLA) cross-talk waveform and estimating a cross-talk weight.

Another notable patent is "Probe Placement for Laser Probing System." This invention features a control system designed for placing an optic probe. It includes a receiver circuit that captures reflected light from the optic probe, generating an LP waveform in response to a trigger signal. A CLA processor simulates an optical response at a target location on the surface of a cell, while a test controller manages the test pattern and updates the position signal to optimize the probe's placement.
