Latest Patents

Among his latest patents is a groundbreaking invention titled "Circuitry and method for critical path timing speculation to enable process variation compensation via voltage scaling." This patent introduces a critical-path timing sensor that detects set-up timing failures from a functional critical path to a path flip-flop. The functional critical path carries test data during test mode and normal data during regular device operation. The invention utilizes an exclusive-OR (XOR) gate to compare the D input and Q output of the path flip-flop, sampling them just after the clock edge. When a timing failure occurs, the system activates a controller to increase the supply voltage (VDD), allowing for lower power consumption or faster operation.

Another notable patent is "Circuitry and method for timing speculation via toggling functional critical paths." This invention involves toggling functional critical path timing sensors that measure delays in critical paths, which are replicas of actual critical paths or representations of worst-case delay paths. The system employs a Toggle flip-flop or Linear-Feedback-Shift Register (LFSR) to drive high-transition-density test patterns. When a delay fails to meet the set-up timing requirement, the timing sensors signal the controller to adjust the VDD accordingly.
