Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Hello,

I wanted to Check the Functional Safety Capability(ISO26262) of our current Platform and check further actions which can help us achieve it.

We are currently using TMS570LC4357 MCU, TPS65381Q1 PMIC and Using Halcogen and CCS tools for Development.

Questions: -

1. General

           a. Is It possible to achieve ISO26262 Compliance in this Platform??

           b. What ASIL Level can be achieved??

2. Tools

    1. HALCOGEN -> I could see that Halcogen-CSP can help in development of Functional Safety Product: -

         a. Can our current Halcogen (www.ti.com/.../HALCOGEN) not generate Safety Complaint code??

         b. Is the Halcogen-CSP gonna generate a different MCAL Stack which is Safety Complaint maybe??

         c. Can the MCAL-Safety-Manual be fulfilled to make the MCAL Stack Safety Complaint??

    2. CCS

          a. can CCS be used for Functional Safety Compliance??

3. Microcontrollers

     1. TMS570LC4357

             a. Is this MCU capable of ASIL C Compliance??

             b. Can the Safety Manual be fulfilled to achieve Safety Compliance?

     2. TPS65381Q1 

             a. Is this PMIC capable of ASIL C Compliance??

             b. Can the Safety Manual be fulfilled to achieve Safety Compliance?

Please do let me know any other Steps that may be required to achieve ASIL Safety Compliance??

Thanks and Regards,

    Hi Sakti,

    1. General

    a. It is possible to achieve ISO 26262 compliance with the TMS570LC4357 MCU and TPS65381Q1 PMIC platform.

    b. The ASIL level that can be achieved will depend on the safety goals and requirements of the specific application. However, the TMS570LC4357 MCU has been certified up to ASIL D and the TPS65381Q1 PMIC up to ASIL B.

    1. Tools

    2. HALCOGEN

    a.

    The HALCoGen SW development process was certified, but the HALCOGen generated code is not certified. 

    The HALCoGen compliance support package (CSP) was developed to provide documentation, reports and unit test capability to assist customers using HALCoGen generated software to comply with functional safety standards such as IEC 61508 and ISO 26262.

    1. CCS

    a. CCS itself is not certified for functional safety, but it can be used to develop safety-related software.

    1. Microcontrollers

    2. TMS570LC4357

    a. The TMS570LC4357 MCU is capable of achieving ASIL C or higher depending on the specific application.

    b. The safety manual for the TMS570LC4357 can be used to help ensure that the MCU is used in a way that is compliant with the ISO 26262 standard.

    1. TPS65381Q1

    a. The TPS65381Q1 PMIC is capable of achieving ASIL B or higher depending on the specific application.

    b. The safety manual for the TPS65381Q1 can be used to help ensure that the PMIC is used in a way that is compliant with the ISO 26262 standard.

    Other steps that may be required to achieve ASIL safety compliance include performing a hazard analysis and risk assessment, implementing safety measures such as redundancy and fault tolerance, and testing and verifying the safety-related functions of the system.

    Hello Jagadish,

    Thank you for your brief reply

    I can see that the Halcogen-CSP Software is a Premium Software and costs 25000 for Multi-project license.

    In this Multi-project License, Can the Halcogen-CSP Softwarebe used on multiple PCs?? Is there a limit on the number of users?

    Thanks and Regards,

    Sakti

    This should need to be check with local sales team, i don't have any information on this.

    Sakti Kumar Padhy said:
    1) What are the Features that it provides???

    The HALCoGen CSP features unit level test cases developed by TI. These test cases can be run using LDRAunit from LDRA. LDRAunit can be purchased directly through LDRA.

    Sakti Kumar Padhy said:

    HALCoGen CSP will not generate any code directly, it will provide the necessary documentation, reports and unit test capability to assist customers using HALCoGen generated software to comply with functional safety standards such as IEC 61508 and ISO 26262.
