A Low-Cost Quadruple-Node-Upsets Resilient Latch Design
In this article, a low-cost quadruple-node-upsets resilient latch (LCQRL) design is proposed. To meet the high-reliability demands of safety-critical applications, the latch integrates nine soft-error-interceptive modules (SIMs) to form robust feedback loops, ensuring complete resilience to quadruple-node upsets (QNUs). Each Sim comprises ten CMOS transistors and a clocked inverter. Notably, C-element (CE) and dual interlocked storage cell (DICE) modules are not employed in this circuit, resulting in a small area and low power consumption. The simulation results verify the complete QNU self-recoverability and cost-effectiveness of this design. Compared with the existing radiation-hardened QNU resilient latches, the LCQRL latch demonstrates significant improvements in area, power consumption, and area-power–delay product (APDP) by 47.8%, 63%, and 75.5%, respectively. Furthermore, it exhibits low sensitivity to process, voltage, and temperature (PVT) variations.
期刊介绍:
The IEEE Transactions on VLSI Systems is published as a monthly journal under the co-sponsorship of the IEEE Circuits and Systems Society, the IEEE Computer Society, and the IEEE Solid-State Circuits Society.
Design and realization of microelectronic systems using VLSI/ULSI technologies require close collaboration among scientists and engineers in the fields of systems architecture, logic and circuit design, chips and wafer fabrication, packaging, testing and systems applications. Generation of specifications, design and verification must be performed at all abstraction levels, including the system, register-transfer, logic, circuit, transistor and process levels.
To address this critical area through a common forum, the IEEE Transactions on VLSI Systems have been founded. The editorial board, consisting of international experts, invites original papers which emphasize and merit the novel systems integration aspects of microelectronic systems including interactions among systems design and partitioning, logic and memory design, digital and analog circuit design, layout synthesis, CAD tools, chips and wafer fabrication, testing and packaging, and systems level qualification. Thus, the coverage of these Transactions will focus on VLSI/ULSI microelectronic systems integration.
