Objective

A top-tier automotive supplier partnered with AVIN Systems to design and develop MCAL and Complex Device Drivers (CDD) for safety-critical ECUs. The objective was to ensure hardware abstraction, faster response, and optimized performance while adhering to AUTOSAR standards.

Solution

Requirement Analysis & Configuration

Defined MCAL and CDD architecture for safety-critical ECUs. Ensured hardware abstraction across AURIX and RH850.

Network Management and Development

Developed low-level drivers for real-time communication and interrupt handling.

Memory and Bootloader Integration

Integrated memory-safe bootloaders for ASIL-compliant ECUs.

Security Enhancement

Applied ISO 26262 and MISRA C standards for secure driver development.

Testing and Validation

Used automated code generation and ASPICE-aligned testing to reduce effort by 35%.

Impacts

  1. Delivered ASIL-compliant drivers meeting ISO 26262.
  2. Reduced development effort by 35% using automated code generation.
  3. Enhanced hardware scalability across MCU families.
