ZC.MuNiu SafetyLibrary Product Manual Based On Flagchip FC7240
Introduction

Currently, the electronic and electrical architecture of automobiles is becoming increasingly complex, and the safety requirements for automotive electronics are also rising. To meet the safety requirements of automobiles, functional safety is gaining more attention. When it comes to functional safety, the first thing that comes to mind is the functional safety standard ISO 26262. In particular, ISO 26262-5(2018) Clause 8 introduces two metrics: Single-point fault metric (single-point fault metric) and Latent-fault metric (latent fault metric). Depending on the required ASIL level, the single-point fault metric and latent fault metric must meet the corresponding levels.

For microcontrollers (MCU, referred to as MCU below), within the electronic and electrical system, they are designed and developed as SEooC (safety element out of context). To meet the aforementioned metric requirements, MCUs need to implement corresponding safety mechanisms. These safety mechanisms can be allocated to both hardware and software modules. The Safety Frame safety library for MCUs is the implementation of safety mechanisms allocated to software.

ØCan be integrated as a complex driver into AUTOSAR .

Ø  Can be integrated into non-AUTOSAR software architectures.

Ø  Support multi-core testing and applications.

Ø  Safety Frame has internal program flow monitoring.

Ø  High security: Supports multi-core self-testing, and can achieve up to ASIL-D requirements when paired with ZC Technology's FS26 SBCDrv.

Ø  High scalability: Each module can be configured to meet the application requirements of different customers.

Configuration Tool:

To meet the diverse project requirements of customers and enhance the scalability of the Safety Library, the FC7240 Safety Library has implemented the configurability of each module and has developed a configuration tool for the Safety Library. Customers can complete the configuration of various modules of the Safety Library using the configuration tool according to different needs. They can generate configuration code files, and integrate the generated configuration files into the project.

Function Summary

The FC7240 Safety Library is designed to assist customers in achieving functional safety requirements based on the FC7240 platform. The Safety Library is highly scalable and can be configured and redeveloped according to different customer project requirements, ultimately meeting the customers' functional safety requirements. 

The FC7240 Safety Library is used to implement the software safety mechanisms of the FC7240, including the testing of internal MCU modules and the driving of hardware safety mechanisms.


Application Field

The FC7240 Safety Library can be applied to controllers that require functional safety levels.

For example:

Ø  Battery Management System

Ø  Advanced Driver Assistance System

Ø  Vehicle Stability Control

Ø  Electric Power Steering

Ø  Chassis Domain Line Control System Applications

Ø Anti-lock Braking System

Ø Active Suspension Control System

By integrating the Safety Library into the control based on FC7240, it is possible to meet the ISO 26262 ASIL-D level requirements.
