Definition Of

The paper presents fault-tolerant CMOS ASICs which are immune to the single event upsets (SEU), the single event transients (SET), and the single event latchup (SEL). Triple and double modular redundant (TMR and DMR) circuits and SEL protection switches (SPS) make the base for a modified fault-tolerant ASIC design flow. The proposed design flow requires the standard design automation tools and a few additional steps during logic synthesis and layout generation. An extra step is necessary to generate the redundant design net-list including voters. Other two extra steps (definition of the redundant power domains and placement of the SPS) have to be performed in the layout phase. The concept has been proven by design and implementation of the two digital circuits: shift-register and synchronous counter.

Static Random-Access Memory (SRAM)-based Field Programmable Gate Arrays (FPGAs) are increasingly being used in many application domains due to their higher logic density and reconfiguration capabilities. However, with state-of-the-art FPGAs being manufactured in the latest technology nodes, reliability is becoming an important issue, particularly for safety-critical avionics, automotive, aerospace, industrial robotics, medical, and financial systems. Therefore, fault tolerant system design methodologies have become essential in the aforementioned application domains. The Isolation Design Flow (IDF) is one such design methodology that has promising prospects due to its ability to isolate logic design modules at the physical level for fault containment purposes. This paper proposes a methodology to evaluate the effectiveness of the IDF. To do so, reverse engineering is used to enable fault injection on the IDF designs with minimal changes in the bit-stream. This reduces the time needed to inject a fault significantly thus accelerating the evaluation process. Then this methodology is applied to a case study of a single-chip cryptography application on a ZynQ SoC. Specifically, an Advanced Encryption Standard (AES) Duplication With Comparison (DWC) design is physically isolated with IDF and subsequently subjected to frame-level Fault Injection (FI) in the configuration memory.
