Available in PDF, EPUB and Kindle. Book excerpt: Reliability is a key concern in VLSI systems and transient/intermittent faults, often caused by soft errors, require designers to create special mitigation techniques. This book describes such techniques, spanning all levels of the design flow, to reduce systematically the vulnerability of VLSI systems to soft errors. Readers will be enabled to address soft error issues early in their design flow, allowing them to weigh the implications of dedicating more resources for soft error detection and prevention, against the correlating impact on delay, power and area.

The emphasis is on modeling approaches and algorithms for analysis and mitigation of soft errors in nano-scale CMOS digital circuits, using techniques that are the cornerstone of Computer Aided Design (CAD) of reliable VLSI circuits. The authors introduce software tools for analysis and mitigation of soft errors in electronic systems, which can be integrated easily with design flows. In addition to discussing soft error aware analysis techniques for combinational logic, the authors also describe new soft error mitigation strategies targeting commercial digital circuits.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: The occurrence of transient faults like soft errors in computer circuits poses a significant challenge to the reliability of computer systems. Soft error, which occurs when the energetic neutrons coming from space or the alpha particles arising out of packaging materials hit the transistors, may manifest themselves as a bit flip in the memory element or as a transient glitch generated at any internal node of combinational logic, which may subsequently propagate to and be captured in a latch. Although the problem of soft errors was earlier only a concern for space applications, aggressive technology scaling trends have exacerbated the problem to modern VLSI systems even for terrestrial applications. In this dissertation, we explore techniques at all levels of the design flow to reduce the vulnerability of VLSI systems against soft errors without compromising on other design metrics like delay, area and power. We propose new models for estimating soft errors for storage structures and combinational logic. While soft errors in caches are estimated using the vulnerability metric, soft errors in logic circuits are estimated using two new metrics called the glitch enabling probability (GEP) and the cumulative probability of observability (CPO). These metrics, based on signal probabilities of nets, accurately model soft errors in radiation-aware synthesis algorithms and helps in efficient exploration of the design solution space during optimization. At the physical design level, we leverage the use of larger netlengths to provide larger RC ladders for effectively filtering out the transient glitches. Towards this, a new heuristic has been developed to selectively assign larger wirelengths to certain critical nets. This reduces the delay and area overhead while improving the immunity to soft errors. Based on this, we propose two placement algorithms based on simulated annealing and quadratic programming which significantly reduce the soft error rates of circuits. At the circuit level, we develop techniques for hardening circuit nodes using a novel radiation jammer technique. The proposed technique is based on the principles of a RC differentiator and is used to isolate the driven cell from the driving cell which is being hit by a radiation strike. Since the blind insertion of radiation blocker cells on all circuit nodes is expensive, candidate nodes are selected for insertion of these cells using a new metric called the probability of radiation blocker circuit insertion (PRI). We investigate a gate sizing algorithm, at the logic level, in which we simultaneously optimize both the soft error rate (SER) and the crosstalk noise besides the power and performance of circuits while considering the effect of process variations. The reliability centric gate sizing technique has been formulated as a mathematical program and is efficiently solved. At the architectural level, we develop solutions for the correction of multi-bit errors in large L2 caches by controlling or mining the redundancy in the memory hierarchy and methods to increase the amount of redundancy in the memory hierarchy by employing a redundancy-based replacement policy, in which the amount of redundancy is controlled using a user defined redundancy threshold. The novel architectures and the new reliability-centric synthesis algorithms proposed for the various design abstraction levels have been shown to achieve significant reduction of soft error rates in current nanometer circuits. The design techniques, algorithms and architectures can be integrated into existing design flows. A VLSI system implementation can leverage on the architectural solutions for the reliability of the caches while the custom hardware synthesized for the VLSI system can be protected against radiation strikes by utilizing the circuit level, logic level and layout level optimization algorithms that have been developed.

This book was released on 2009-10-22 with total page 224 pages. Available in PDF, EPUB and Kindle. Book excerpt: This monograph is motivated by the challenges faced in designing reliable VLSI systems in modern VLSI processes. The reliable operation of integrated circuits (ICs) has become increasingly dif?cult to achieve in the deep submicron (DSM) era. With continuouslydecreasing device feature sizes, combinedwith lower supply voltages and higher operating frequencies, the noise immunity of VLSI circuits is decreasing alarmingly. Thus, VLSI circuits are becoming more vulnerable to noise effects such as crosstalk, power supply variations, and radiation-inducedsoft errors. Among these noise sources, soft errors(or error caused by radiation particle strikes) have become an increasingly troublesome issue for memory arrays as well as c- binational logic circuits. Also, in the DSM era, process variations are increasing at a signi?cant rate, making it more dif?cult to design reliable VLSI circuits. Hence, it is important to ef?ciently design robust VLSI circuits that are resilient to radiation particle strikes and process variations. The work presented in this research mo- graph presents several analysis and design techniques with the goal of realizing VLSI circuits, which are radiation and process variation tolerant.

Available in PDF, EPUB and Kindle. Book excerpt: Nanoscale Memristor Device and Circuits Design provides theoretical frameworks, including (i) the background of memristors, (ii) physics of memristor and their modeling, (iii) menristive device applications, and (iv) circuit design for security and authentication. The book focuses on a broad aspect of realization of these applications as low cost and reliable devices. This is an important reference that will help materials scientists and engineers understand the production and applications of nanoscale memrister devices. A memristor is a two-terminal memory nanoscale device that stores information in terms of high/low resistance. It can retain information even when the power source is removed, i.e., "non-volatile." In contrast to MOS Transistors (MOST), which are the building blocks of all modern mobile and computing devices, memristors are relatively immune to radiation, as well as parasitic effects, such as capacitance, and can be much more reliable. This is extremely attractive for critical safety applications, such as nuclear and aerospace, where radiation can cause failure in MOST-based systems. - Outlines the major principles of circuit design for nanoelectronic applications - Explores major applications, including memristor-based memories, sensors, solar cells, or memristor-based hardware and software security applications - Assesses the major challenges to manufacturing nanoscale memristor devices at an industrial scale
