An automotive driver-assistance controller board with two identical processor packages side by side, next to a larger processor, memory, power components and a row of connectors, all on one PCB.

The Core Concept of Dependent Failure Analysis in ISO 26262

Two redundant channels are not automatically independent. What a dependent failure is, the difference between common cause and cascading failures, the coupling factors that tie elements together, and why ISO 26262 asks for DFA.
