    • A parallel virtual instrumentation framework for improving diagnostic efficiency in bed-of-nails testers 

      Chamunorwa, T.; Musiiwa, P. B.; Zvavashe, T.; Rushambwa, M. C.; Tyavlovsky, A.; Svistun, A. I. (БНТУ, 2025)
      Conventional sequential PCB testers are inefficient, as a single failure halts all subsequent tests, leading to incomplete diagnostic data and delayed fault isolation. This study proposes a parallel virtual instrumentation framework in LabVIEW to overcome these limitations. By leveraging asynchronous execution, the framework runs multiple independent tests concurrently, continuing ...

    • An investigation into the power-performance trade-off in memristor-augmented sense amplifiers for nanoscale SRAM 

      Musiiwa, P. B.; Rushambwa, M. C.; Gwamuri, J.; Kanhukamwe, Q. C.; Tyavlovsky, A.; Svistun, A. I. (БНТУ, 2025)
      As technology ramps up to high nodes, SRAM sense amplifiers struggle suffer from increasing static power. The paper proposes memristors as non-volatile, tunable loads in cross-coupled differential sense amplifiers as a remedy. Simulation in a 45 nm node reveals 69.2 % leakage power reduction, making the solution appealing for low-power usage. The static power reduction comes at ...
