Latest Patents

Raghavan's latest patents include advancements in programmable delay test circuitry and feature control circuitry for testing integrated circuits. The programmable delay test circuitry is designed to test a circuit under test on an integrated circuit. It utilizes logic circuitry to output an error signal when the delay time provided by the circuit under test exceeds a characteristic time that can be programmed into the circuitry. This innovative design includes a logic gate that generates a pulse with a width equal to the delay of the delay circuitry. Additionally, the programmable delay test circuitry features a programmable load that can be set to a specific characteristic time, asserting an error signal when the delay time surpasses this threshold.

The feature control circuitry for testing integrated circuits includes testing circuitry for input-output circuits. This integrated circuit comprises input-output circuits with associated input-output pins and buffers. Each input-output circuit is equipped with features such as weak pull-up, voltage clamp diode, bus hold, open-drain, differential input termination resistance, and single-ended/differential mode selection. A feature control register receives instructions for feature selection, allowing for systematic testing of the input-output circuit features.
