Latest Patents

One of Szczepan Urban's latest patents is titled "Suspect resolution for scan chain defect diagnosis." This application discloses a computing system that implements an automatic test pattern generation tool to perform scan chain diagnosis-driven compaction setting. The system can perform fault simulation on scan chains in a circuit design describing an integrated circuit. It loads test patterns to the simulated scan chains and unloads test responses from them. The computing system determines the locations of sensitive bits and unknown bits in each of the scan chains based on the test responses. It generates a configuration for a compactor in the integrated circuit based on these locations, allowing for effective compaction of test responses.

Another significant patent is "Reversible multi-bit scan cell-based scan chains for improving chain diagnostic resolution." This circuit comprises a scan chain with multi-bit flip-flops, multiplexers, and new scan enable signal generation circuitry. Each multiplexer is associated with a specific bit of the flip-flops and is configured to select between an input signal from functional circuitry and an input signal from a data output of a bit of the scan chain. The new scan enable signal generation circuitry produces a new scan enable signal based on the scan direction control signal and a scan enable signal for the scan chain.
