Впровадження DO-254 в процес розробки регуляторів авіадвигунів

New, Fast and Efficient DO-254 Verification Methodology

This White Paper points out the most significant issues which can be encountered during DO-254 compliant verification process for FPGA designs. It proposes the methods of saving development time during the functional verification process, reusing the work done during RTL simulation and performing the in-hardware at-speed testing in target FPGA devices assuring at the same time a high visibility...

Software and hardware certification of safety-critical avionic systems: A comparison study

a r t i c l e i n f o Keywords: Software and hardware quality assurance Airborne software and hardware Safety certification DO-178B DO-254 To ensure the safety of avionic systems, civil avionic software and hardware regulated by certification authorities must be certified based on applicable standards (e.g., DO-178B and DO-254). The overall safety integrity of an avi-onic system, comprising sof...

Osteoarthritis (OA), also erroneously called degenerative joint disease, represents failure of a diarthrodial joint. In idiopathic OA, the most common form of the disease, no predisposing factor is apparent. Secondary OA is pathologically indistinguishable from idiopathic OA, but is attributable to an underlying cause, such as trauma or metabolic and endocrine diseases.1 Major trauma and repeti...

Mammalian mitochondrial DNA (mtDNA) is inherited principally down the maternal line, but the mechanisms involved are not fully understood. Females harboring a mixture of mutant and wild-type mtDNA (heteroplasmy) transmit a varying proportion of mutant mtDNA to their offspring. In humans with mtDNA disorders, the proportion of mutated mtDNA inherited from the mother correlates with disease sever...
