4. Electronic Control Unit—Power—These are general ECU hardware require-
ments related to power, sleep current, wake-up, efficiency, hardware in-
put/output, cold crank operation, and EMC.

DFSS Conceptualize Phase— Here requirements were first classified for software
and hardware and then subclassified for redundancy and safety. Based on the en-
gineering judgment, understanding the requirements in detail, the “Program Plan”
