UNTERPREMSTAETTEN, Austria--Analog IC provider AMS announced it's nearing volume production of its first ISO26262 functional safety standard automotive products.
AMS device applications with ISO26262 qualification cover electric power steering, pedal and position sensors. The first products developed along the standard are now approaching production release in early 2013.
Safety-related design activities at AMS have led to a large portfolio of advanced diagnosis IP such as
- Continuous integrity checks for on-chip-memory
- Self-test of the signal processing blocks
- Read-back of the status of device-drivers and outputs
Released in 2011, the ISO26262 standard is the major global regulation
governing functional safety in road vehicles. A growing share of safety
critical systems under development in the automotive industry today
follows this standard. The severity of a possible failure in an
automotive system leads to the assignment of an Automotive Safety
Integrity Level (ASIL) to it. Levels of A, B, C or D exist with D being
the most critical.
The ASIL then in turn demands a maximum
failure rate and a minimum percentage of “safe” failures with respect to
all failures the system can have in operation. To ensure a high share
of safe failures, on-chip safety and diagnosis functions are required
for any semiconductor devices present in the system. The standard also
provides a framework for the validation and documentation of the safety
