Functional Safety Solution "Hitex SafeTpack Software" for Infineon AURIX TC3xx

On this page, Hitex (high tech) companyHere is an overview of our functional safety solution "SafeTpack".

1. Overview of SafeTpack

Hitex's SafeTpack is a functional safety software solution for Infineon's AURIX™ TC3xx automotive microcontrollers.

With the introduction of SafeTpack, even when designing and building a safety application from scratch, it is expected that the targeted level of functional safety can be achieved quickly.

2. CHALLENGES IN DEVELOPING FUNCTIONAL SAFETY COMPLIANT APPLICATIONS

System integrators are responsible for complying with the functional safety standard ISO-26262 (*1) when developing automotive applications that require functional safety using AURIX™ TC3xx. Projects with particularly high safety requirements may require ASIL-D (*2).

Infineon provides a safety manual for this, the document is over 1000 pages and is intended for experienced functional safety engineers. Therefore, system integrators often spend a lot of time and effort understanding this and implementing the necessary safety mechanisms.

 

*1 ISO-26262 : International standard for functional safety related to automobile electrical/electronics

*2 ASIL: Abbreviation for Automotive Safety Integrity Level. Classified into A, B, C, and D, with ASIL-D being the highest functional safety level

I have no experience in developing functional safety with AURIX™ TC3xx, so I am not sure about the implementation method and the cost...

3. Solution by SafeTpack

Macnica proposes Hitex 's SafeTpack as a solution to the above issues faced by our customers.

SafeTpack covers most safety use cases for ASIL-A to ASIL-D compliant applications, providing a shortcut to implement AURIX™ safety manual requirements. SafeTpack is also PRO-SIL™ (*3) compliant, facilitating ISO-26262 compliance for applications using AURIX™. Since the introduction of SafeTpack reduces the complexity of functional safety development, customers benefit from being able to concentrate on developing their applications.
