exida vs NOVO Engineering: overview
exida
exida was founded in 2000 and is headquartered in Sellersville, Pennsylvania. The company grew out of founder Dr. William Goble's relationship with TÜV Bayern during a product safety certification process and has since become one of the few product safety certification bodies in the world, providing consulting, certification, and lifecycle management for IEC 61508, IEC 61511, IEC 62443, and ISO 26262. Its ARCHx knowledge base embeds more than 30 years of accumulated hardware, software, FPGA, and cybersecurity design and analysis experience. For a firmware program that needs a certification body's opinion rather than just a consultant's opinion, exida is the more direct fit of any firm on this list.
NOVO Engineering
NOVO Engineering was founded in 2004 and is headquartered in Vista, California near San Diego, with a second location near Minneapolis and a team reported between 48 and 60 engineers averaging 16 years of experience each. Its systems-engineering framing means firmware architecture advisory is delivered alongside mechanical and electrical systems review from the earliest stages of a program, across medical devices, biotech instrumentation, and commercial products. For a buyer whose architecture question spans more than firmware alone, that senior, multi-discipline systems-engineering bench is the specific value.
