B.3 Information Provided

Texas instruments has summarized what it considers the most critical functional safety work products that are available to the customer either publicly or under a nondisclosure agreement (NDA). NDAs are required to protect proprietary and sensitive information disclosed in certain functional safety documents.

Table 8-2 Product Functional Safety Documentation
Deliverable Name Contents
Functional Safety Product Preview Overview of functional safety considerations in product development and product architecture. Delivered ahead of public product announcement.
Functional Safety Manual User guide for the functional safety features of the product, including system level assumptions of use.
Functional Safety Analysis Report Results of all available functional safety analysis documented in a format that allows computation of custom metrics.
Functional Safety Report(1) Summary of arguments and evidence of compliance to functional safety standards. References a specific component, component family, or TI process that was analyzed.
Assessment Certificate(1) Evidence of compliance to functional safety standards. References a specific component, component family, or TI process that was analyzed. Provided by a 3rd party functional safety assessor.
(1) When an Assessment Certificate is available for a TI functional safety product, the Functional Safety Report may not be provided. When a Functional Safety Report is provided, an Assessment Certificate may not be available. These two documents fulfill the same functional safety requirements and will be used interchangeably depending on the TI functional safety product.
