Few people realise that it also refers to a test method called ‘boundary scan’, and even then they probably couldn’t say exactly what this means. As early as the 1980s it became clear that traditional measurement methods using instruments such as multimeters and oscilloscopes would eventually become unfeasible due to the ongoing miniaturisation of electronic devices.
