“…In addition to oil-and-gas industry, integrated microcircuits designed for high-temperature operation are relevant in aviation electronics (avionics) and astronautics [20]. In the modern projects of MoreElectronicAircraft program (MEA), preference is given not to central onboard computer, but to variety of distributed components -microcontrollers and microprocessors.…”

The current geopolitical situation and import–substitution challenges facing the domestic electronics industry require the creation of devices capable of reliably functioning in extreme environmental conditions, at particularly high temperatures. When developing electronic devices that must function reliably in temperature range beyond the usual values, developers should rely on cooling, active or passive. There may be situations when cooling is impractical or impossible. The operation of the device in special temperature range, in some situations, makes perfect sense if it provides reduction in the cost of the device or increase in its reliability. In such situations, it is necessary to solve many complex problems, including semiconductor manufacturing technology, design and testing methods. The article examines the issues of creating high–temperature electronics components necessary for the long-term development of the domestic oil–and–gas and aerospace industries. Creation of import-substituting technologies for intelligent wells makes it possible to reduce significantly the cost of equipment. In aerospace industry, this problem is even more actual: the cost of “western” computing devices for use in space reaches half million euros, and under the conditions of sanctions, its purchase may not be available, while similar import-substituting domestic device is up to 10 times cheaper. Flights to near and far space require, in addition to high radiation resistance, the reliability of all spacecraft systems in the wide temperature range. Article presents technical characteristics of the main analog chips designed to operate at temperatures up to +125 ° C.

“…The consideration of a QDI asynchronous logic design is motivated by important factors such as innate resilience to electromagnetic interference [19], inherent tolerance to parametric variations [20] and harsh environmental phenomena [21], low power operation [22], and natural resistance to power analysis attacks [23], all of which are relevant for mission-and safety-critical applications.…”

Electronic circuits and systems employed in mission-and safety-critical applications such as space, aerospace, nuclear plants etc. tend to suffer from multiple faults due to radiation and other harsh external phenomena. To overcome single or multiple faults from affecting electronic circuits and systems, progressive module redundancy (PMR) has been suggested as a potential solution that recommends the use of different levels of redundancy for the vulnerable portions of a circuit or system depending upon their criticality. According to PMR, triple modular redundancy (TMR) can be used where a single fault is likely to occur and should be masked, and quintuple modular redundancy (QMR) can be used where double faults are likely to occur and should be masked. In this article, we present asynchronous QDI majority voter designs for QMR and state which are preferable from cycle time (i.e., speed), area, power, and energy perspectives. Towards this, we implemented example QMR circuits in a robust QDI asynchronous design style by employing a delay insensitive dual rail code for data encoding and adopting four-phase handshake protocols for data communication. Based on physical implementations using a 32/28nm CMOS process, we find that our proposed QMR majority voter achieves improved optimization in speed and energy.

“…Various asynchronous digital circuits are designed and commercialized by the leading companies such as IBM, Intel, Philips Semiconductors, Sun Microsystems (now Oracle), etc., [63][64][65][66][67] over the last two decades with considerable cost benefits. Several successful industrial experiments have also been performed to support the asynchronous circuit design such as Intel RAPPID [68], IBM FIR filter [69,70], optimizing continuous-time digital signal processors [71,72], developing ultra-low-energy devices [73][74][75][76], system design to handle extreme temperature [77] and finally, developing alternative computing paradigms [78][79][80]; however, these experiments were not commercialized. One of the primary reasons for the absence of commercial asynchronous circuits is the absence of sufficiently mature asynchronous EDA tools [51,81].…”

Asynchronous Floating-Point Adders and Communication Protocols: A Survey

Addition is the key operation in digital systems, and floating-point adder (FPA) is frequently used for real number addition because floating-point representation provides a large dynamic range. Most of the existing FPA designs are synchronous and their activities are coordinated by clock signal(s). However, technology scaling has imposed several challenges like clock skew, clock distribution, etc., on synchronous design due to presence of clock signal(s). Asynchronous design is an alternate approach to eliminate these challenges imposed by the clock, as it replaces the global clock with handshaking signals and utilizes a communication protocol to indicate the completion of activities. Bundled data and dual-rail coding are the most common communication protocols used in asynchronous design. All existing asynchronous floating-point adder (AFPA) designs utilize dual-rail coding for completion detection, as it allows the circuit to acknowledge as soon as the computation is done; while bundled data and synchronous designs utilizing single-rail encoding will have to wait for the worst-case delay irrespective of the actual completion time. This paper reviews all the existing AFPA designs and examines the effects of the selected communication protocol on its performance. It also discusses the probable outcome of AFPA designed using protocols other than dual-rail coding.
