“…Similar to Kaliorakis et al [8], conducted experiments aim to evaluate and provide insights on how to improve the accuracy of FI frameworks based on virtual platforms. Our work differs from [5], concerning the investigation of multicore systems, is that we introduce the discussion on the different cross-compilers and parallel programing models (i.e. Serial, MPI, and OpenMP), considering four cores and the NAS Parallel Benchmarks (NPB) [25].…”

“…Second, the simulation time at this level is exceptionally high. This made the simulation speedup of fault injection campaigns one of the leading motivations found in the literature to use virtual platforms [5,8]. In this sense, our first experiment is to quantify the simulation speed for each of the adopted applications, as shown in Figure 2.…”

“…cross-compilers) and the soft error consistency analysis focus on a JIT-based virtual platform. An initial effort to evaluate the soft error assessment consistency of a JIT-based FI framework is described in [5]. In this work, a Fault Injection Module (FIM) was integrated into gem5 and OVPsim.…”

“…Some simulators are based on high level behavioural models and some based on hardware description language level (HDL) or gate level models. Although, HDL level and gate level models are more accurate than high behavioural models, there are two main problems when using HDL or gate level descriptions: commercial processors are rarely available to users and the necessary time to simulate detailed commercial multicore processors is extremely high, making the soft error analysis of emerging multicore processors impractical [5].…”

“…While the gain in simulation speed is trivially observed in VP simulators based on just-in-time (JIT) dynamic binary translation, the soft error assessment consistency of underlying fault injection frameworks remains unclear. An initial effort to investigate the soft error consistency of VP simulators has been conducted in [5,8,9]. Common findings of these works is that higher level FI approaches provide more flexibility and simulation performance at the cost of accuracy, mostly resulting from the lack of microarchitecture and timing modelling aspects.…”

Soft error resilience has become an essential design metric in electronic computing systems as advanced technology nodes have become less robust to high‐charged particle effects. Designers, therefore, should be able to assess this metric considering several software stack components running on top of commercial processors, early in the design phase. With this in mind, researchers are using virtual platform (VP) frameworks to assess this metric due to their flexibility and high simulation performance. In this regard, herein, this goal is achieved by analysing the soft error consistency of a just‐in‐time fault injection simulator (OVPsim‐FIM) against fault injection campaigns conducted with event‐driven simulators (i.e. more realistic and accurate platforms) considering single and multicore processor architectures. Reference single‐core fault injection campaigns are performed on RTL descriptions of Arm Cortex‐M0 and M3 processors, while gem5 simulator is used to multicore Arm Cortex‐A9 scenarios. Campaigns consider different open‐source and commercial compilers as well as real software stacks including FreeRTOS/Linux kernels and 52 applications. Results show that OVPsim‐FIM is more than 1000× faster than cycle‐accurate simulators and up to 312× faster than event‐driven simulators, while preserving the soft error analysis accuracy (i.e. mismatch below to 10%) for single and multicore processors.

You may never know what results come from your action, but if you do nothing there will be no results." -Mahatma Gandhi AGRADECIMENTOS Agradeço a Deis em primeiro lugar por me acompanhar em todos os momentos da minha vida, principalmente durante as dificuldades. A família é a principal estrutura na vida de um grande homem e a minha está sempre ao meu lado. Agradeço a meus pais CARLOS ALBERTO DORNELLES ABICH, vulgo Dornellão, e ELANE ABICH, minha mãe, por me ensinar que com trabalho duro, respeito, dignidade e caráter se atinge qualquer objetivo. Vocês literalmente fizeram um baita doutor. PAULA ANDRESSA FISCHER, toda vez que eu preciso falar de ti eu sinto que fui abençoado em te ter ao meu lado. Se pudesse desejar algo melhor para esse mundo, desejaria que existissem mais pessoas como você. Só nós sabemos o que passamos nestes últimos anos. Obrigado por existir, e obrigado por estar ao meu lado, sempre, independente dos obstáculos que temos no nosso caminho. A tua compania da mais sentido a minha trajetória. Com esta conquista, até que enfim tu vai poder casar... Te amo. Caros RICARDO AUGUSTO DA LUZ REIS e LUCIANO COPELLO OST, haja insistência, paciência e café comigo né! Mas vamos aos fatos. À quem ler este pedaço da tese, entenda que essas duas pessoas são incríveis. Não estou falando de curriculo e parte técnica. O Reis é meu segundo pai, literalmente, acho que a admiração que um filho tem por um pai ja é o suficiente para exemplificar o que eu sinto. Ost, é como um irmão mais experiênte (pra não dizer mais velho), que sempre buscou que eu não cometesse os mesmos erros que ele, que eu evoluisse a cada passo, que me dava a mão para levantar a cada tropeço e um pontapé para não ficar resmungando ao invés de trabalhar. Sem contar as viagens, os 20 dias que passei com o Ost em Leicester e os churrascos do grupo. Obrigado por tudo isso. Agora vamos além! Aos colegas de laboratório. O RAFAEL FRAGA GARIBOTTI, obrigado pelos auxilios nos artigos e pelas conversas, certamente me esclareceram muita coisa com tua experiência de vida profissional e de estudos. JONAS FOGLIARINI GAVA, e sua paciência, valeu pelos auxilios nos artigos e pela parceria. O MATEUS PAIVA FOGAÇA, meu irmão de pós graduação, obrigado pela amizade, conversas e apoio durante todo este trabalho. Ao VITOR VIANA BANDEIRA e ao FELIPE TODESCHINI BORTOLLON, pelas caronas, trabalhos, churras e parceria. Leo Brendler e Leo Barlette pelas parcerias e pelas conversas descontraídas no laboratório. Mais além, Mateus, Alexandra, Calebe,
