ZC.MuNiu SafetyLibrary Product Manual Based on NXP MPC5744P

Product Description

The MPC5744P Safety Library is designed to assist customers in achieving functional safety requirements based on the MPC5744P 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.

Introduction

The MPC5744P Safety Library is used to implement the software safety mechanisms of the MPC5744P, including the testing of internal MCU modules and the driving of hardware safety mechanisms.

Detailed Introduction

Product Feature

Ø Can be integrated as a complex driver into AUTOSAR .

Ø Meet the different safety level requirements of the controller.

Ø Can be integrated into non-AUTOSAR software architecture.

Ø High scalability: Each module is configurable to meet different customer requirements.

Ø Internal Program Flow Monitoring of the Safety Library.

Configuration Tool

To meet the diverse project requirements of customers and enhance the scalability of the Safety Library, the MPC5744G 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.

Run Phase

Ø Pre-run Phase

This phase involves testing the safety mechanisms of the MCU. During this phase, the FCCU is in the Normal state, and it is generally conducted before the OS starts up.

Ø Run Phase

This phase occurs while tasks are running. The FCCU remains in the Normal state during this phase, which takes place while the OS is in operation.
