Hardware Robustness for SMI Register Interfaces in Automotive PHY ChipsDuration : 6 monthsLocation : Eindhoven, Netherlands (hybrid)Background and MotivationAutomotive PHY devices expose their configuration and status registers over the Serial Management Interface (SMI), a two-wire serial bus (MDC / MDIO) defined by IEEE 802.3 Clause 22/45.In the current implementation, the SMI link carries no inherent data-integrity protection: there is no parity bit, no CRC, and no acknowledgment mechanism in the baseline protocol.In a harsh automotive EMC environment, single-bit upsets on the MDIO bus can silently corrupt a register write, causing a PHY to enter an incorrect operating mode without any indication to the host.To guard against this, the software driver currently performs write-then-read-back verification and double-read redundancy checks.These software workarounds increase bus utilization, add latency to every configuration transaction, and consume CPU cycles in a safety-critical context.This internship investigates and prototypes hardware-based robustness mechanisms that can detect or correct bit errors on the SMI bus, or within the on-chip register file, transparently to the software layer.
