Part Number: TMS570LC4357
Other Parts Discussed in Thread: HALCOGEN

Hello. I'm Choi from South Korea.

Using TMS570LC4357, I'm developing a product using TMS570LC4357.

I'd like to perform a safety diagnosis using SafeTI Diagnostic Library that TI provides. 

Also I have to get a safety certification. For those, I need Static and dynamic analysis results about provided source.

I think that Compliance Support Package(CSP)  is the result that I want.

I confirmed that TMS570LC4357 is the CSP supported product. (below images)

Please let me know procedure to receive CSP or how I can receive the Compliance Support Package (CSP).

Sincerely thanks for your reply.

    Hi Choi,

    For a functional safety system, it is very important to have a solid foundation with adherence to functional safety standards with which to start. TI provides a strong foundation for the software stack through HALCoGen (Hardware Abstraction Layer Code Generator) and the SafeTI Diagnostic Library. These software components provide low-level peripheral drivers, device initialization and diagnostic functions for Hercules MCUs. Since they have been developed by following the ISO 26262 and IEC 61508 safety standards, they can be used by the customer assist in the development of their functional safety systems. The software development process for these software components has been certified by TÜV NORD to meet ASIL D and SIL 3 levels of safety integrity. TÜV NORD is an internationally recognized and independent assessor of compliance to quality and safety standards.

    A functional safety system designer is responsible for creating systems (hardware+ software) that meet all applicable safety, regulatory and performance requirements. When the system is submitted for functional safety certification, all the software components are assessed to determine compliance to functional safety standards. This is a monumental task for the system developer if they are to provide all the artifacts for all the software components coming from different vendors. SafeTI compliance support packages (CSP) help make this task easier for the system developer. SafeTI Compliance Support Packages are developed according to TI’s certified software development process and are available for HALCoGen and the SafeTI Diagnostic library. These CSPs provide a helpful starting point for customers who need to provide similar evidence for their functional safety software. The LDRA tool suite is used in the development of the CSPs.

    The SafeTI CSPs provide documentation, reports and a unit test capability to assist customers using the Hercules MCU software components to comply with functional safety standards such as IEC 61508 (Industrial Controls) and ISO 26262 (Automotive). The test reports include Static Analysis Report and Dynamic Analysis Report.

    Please make a request here:

    You will get response and approval in a couple of days.

    I found "TMS570LC43X SDL-CSP Not available".

    So here is some questions.

    1. Does it mean that TMS570LC4357 is not supported about CSP? (but only support SDL?)

    2. On SDL-CSP, what is the deference between "Not Available" and "Supported"?  ("Not Available" means "Not for free"?)
