1. Does the Safety Peripheral Drivers *replace* the real time driver or augments it?
2. Are both of these (or one or none) are provided in source form?
3. Is there any per-unit royalty when the source is included in shipping firmware?
4. Is the licensing per dev kit/per user/reference counted in some other way or is it unlimited use within the organization once purchased?
5. Do these come with any kind of safety certification?
Best regards

Hi Durga Choudhury,
1. Augments/complements RTD. The SPD Product Brief and SAF Product Brief mentions “complements the S32 Real Time Drivers (RTD)” to cover safety-related on-chip peripherals, and other NXP material says SPD SAF requires/targets specific compatible RTD packages rather than replacing them.
2. Yes. The S32K3 SAF DELIVERABLES list “Source code, User manuals, SAF demo application,” and the S32K3 SPD Deliverables similarly list “Source code, User manuals, SPD demo application.”
3.4. Please communicate with your chosen distributor.
5. They come with functional-safety process compliance and safety collateral, not automatic certification of your ECU/system.
SAF is described as ISO 26262 functional-safety compliant, developed as SEooC, and usable for integration up to ASIL D; SPD material similarly says ISO 26262 functional-safety compliance up to ASIL D.
Safety packages contain SAF Safety Manual, Safety Analysis FMEA, Fault Coverage Estimation. When downloading SAF/SPD, you can download something like SW32K3_SPD_1.0.6_SafetyPack.zip.
Best Regards,
Robin
Hello @Robin_Shen
Thanks for the clarification. On topics 3 &4: We are a United States based company. So we buy the licenses (if we decide to do so) from a distributor? I tried the Digikey site and it brings me back to your site on this topic. Can you please provide a specific contact information (such as a URL/email address etc)?
Best regards

SPD is free of charge.
NXP no longer provides the SAF EVAL version. The FULL SAF version is now available also for development purposes only under NDA.
The following is information I received from the internal team:
Customers interested in obtaining the SAF license for development should go through their respective distributors. Distributors have direct contacts with NXP representatives, who can issue a quote to the customer. If the customer accepts the terms, the software can be provided.
