Testing
•Just like in software, embedded systems need to be
tested and debugged
•However, in these systems, testing includes multiple facets!
–Chip/component verification
–Circuit boards / External devices
–Software, including system startup and configuration
•Hardware has a much higher penalty for correctness mistakes
– You can’t “patch” hardware
–Recalls are expensive (on several levels)
