Latest Patents

Varadarajan holds a patent for his work titled "DFT techniques to reduce test time and power for SoCs." This technique focuses on minimizing the overhead associated with daisy chain test modes in divide-and-conquer testing. By utilizing intermediate test modes that do not span all cores or flip-flops in the core, he has developed a method that allows for a more efficient testing process. The partial residual test mode he introduced spans a subset of the cores, which helps to limit the number of cores involved in a full residual test mode. His algorithms analyze core interactions and create data structures to identify these intermediate test modes. The implementation of a reconfigurable scan segment architecture allows these modes to work with various test compression solutions, leading to substantial improvements in test application time and peak power.
