Abstract(in English) The continuous pursuing of smaller technology nodes makes modern Integrated Circuits (ICs) more and more susceptible to soft-errors. Many radiation-hardened latch designs have been proposed to tolerate soft-errors for reliable LSI designs. However, these existing hardened latches can suffer from reliability issues after production because production defects in such hardened latches are difficult to detect with conventional scan testing. In our previous works, we improved the defect detectability of these hardened latches by adding design-for-test (DFT) technique. A hardened latch design, called high performance scan-test-aware hardened latch (HP-STAHL), was proposed for higher defect detectability, higher soft-error tolerability, and lower propagation delay. However, the added DFT structure in HP-STAHL can partially reduce its soft-error tolerability. In this paper, we propose a novel high performance scan-test-aware hardened latch design with improved soft-error tolerability (HP-STAHL-I) by applying a novel design to offset the reduced soft-error tolerability. Simulation results show that HP-STAHL-I provides higher soft-error tolerability than HP-STAHL. HP-STAHL-I also has lower delay and power delay product (PDP) than the standard latch, demonstrating its high performance.
