Complex systems — whether a system-on-chip or autonomous vehicles — can frustrate design engineers who, after months of painstaking work, have to go back and verify that the system they just designed actually performs the way they intended.
SoCs and autonomous vehicles (AVs) are both built in a “black box,” which by nature makes it hard to find bugs “hiding in places that you don’t think about,” said Ziv Binyamini, CEO and co-founder of a Tel Aviv-based startup called Foretellix.
In testing and verifying an SoC, two measures are deemed essential: “code coverage,” which tells how well the code is tested by stimulus, and “functional coverage,” a way for the user to write certain instrumentation logic that monitor how well the stimulus is covering various functions.
Foretellix believes that similar coverage-driven disciplines should apply to AVs when car OEMs test safety.
