“…The second method avoids the costly fabrication of experimental samples in the cycles of testing, redesign, and therefore is used by many developers. Many implementations of hardware and software solutions to control the operability of the SoC under conditions of exposure to cosmic radiation are well known (in particular, [2][3][4][5]). There are solutions based on FPGA prototyping, which provide the optimal ratio of price and performance of HSS [6].…”

Представлена совокупность разработанных модулей, образующих ядро программного обеспечения экспериментального образца программно-аппаратного комплекса (ПАК) контроля сбоеустойчивости проекта микросхемы. Контроль сбоеустойчивости основан на использовании расширенного метода внесения неисправностей, подразумевающего моделирование многоуровневого воздействия неисправностей. Программные модули ПАК обеспечивают обработку проекта микросхемы, генерацию списка сбоев, генерацию тестовых воздействий и обработку результатов моделирования. Технические решения, воплощенные в ПАК, позволяют выполнять гибкий выбор источников возникновения сбоев в микросхеме и получать детальную информацию о локализации критических сбоев, приводящих к отказу моделируемой системы. Использование ПЛИС-прототипирования вместо программных симуляторов при моделировании позволяет добиться ускорения процесса контроля сбоеустойчивости. A set of developed modules that form the software core of the experimental prototype of a hardware-software system (HSS) for control of fault tolerance of IC design is presented. Control of fault tolerance is based on the use of the extended method of fault injection, which implies the modeling of the multi-level impact of faults. Software modules of HSS provides processing of the IC design, generation of the list of faults, generation of test inputs and processing of the simulation results. Technical solutions embodied in the HSS, allow a flexible choice of sources of faults in the chip and obtaining detailed information about the localization of the critical faults that caused a failure of the simulated system. The use of FPGA prototyping instead of software simulation allows to accelerate the control of fault tolerance. Р азработка устройств типа "система на кри-сталле" (СнК) включает в себя решение целого комплекса взаимосвязанных задач от про-ектирования структуры и выбора аппаратной базы до реализации экспериментальных образ-цов. При этом, проведение тестирования рабо-тоспособности на этапе разработки имеет пер-востепенное, а для устройств на основе заказ-ных и полузаказных микросхем -критическое значение, так как качество тестирования суще-с т в енно в ли яе т на с тои мо с т ь ра зраб о ток. К устройствам специального назначения (в част-ности, компонентам космической техник и) предъявляются дополнительные требования по обеспечению работоспособности в условиях воздействия агрессивных внешних сред. В связи с этим, актуально тестирование сбоеустойчиво-сти устройств типа СнК на этапе их разработки.

“…One way to obtain additional shielding is adding an aluminum coat of 1.5 mm that might prevent permanent errors in the devices (Burlyaev and van Leuken, 2014). Additionally, SEL and SEU's effects can be prevented by software through the use of Cyclic Redundancy Check (CRC) algorithms in subsystems communication, as well as through storing backup copies of each subsystem software in the master system and the use of checksum fields in stored data.…”

The Sergio Arboleda University is preparing its next satellite mission, named Libertad 2. It will carry out a system of image acquisition as a working tool for researches based on the obtained data. Complete methodologies are often used in the development of satellite missions for planning, execution and deployment, for example, the standards of the European Cooperation for Space Standardization; these methodologies, however, do not include technical specifications or requirements for the development of nano-satellites nor for their subsystems. For this reason, this article focuses on the identification of the characteristics, requirements and restrictions, which must be considered in the design of a remote sensing system for satellites under the CubeSat standard, in order to serve as a starting point for the development of the main payload of the Libertad 2 mission.

“…This solution will not only reduce space and weight but also improve the fault tolerance. First, a protection against faults from radiation will be easier to put into practice, using for example shielding [10]. Second, as each processor can carry out any computation (which is the opposite of the standard when each system has its own dedicated processor), the designed algorithm can use spatial redundancy and a CubeSat will remain operational in case of permanent processor failure.…”

CubeSats are small satellites operating in harsh space environment. In order to ensure correct functionality on board despite faults, fault tolerant techniques taking into account spatial, time and energy constraints should be considered. This paper presents a software-level solution taking advantage of several processors available on board. Two online scheduling algorithms are introduced and evaluated. The results show their performances and the trade-off between the rejection rate and energy consumption. Last but not least, it is stated that ordering policies achieving low rejection rate when using the algorithm scheduling all tasks as aperiodic are the "Earliest Deadline" and "Earliest Arrival Time". As for the algorithm treating arriving tasks as aperiodic or periodic tasks, the "Minimum Slack" ordering policy provides reasonable results.
