Design Assurance Pack

SAFERTOS is supplied with a Design Assurance Pack (DAP) which contains every design artifact produced during the full development life cycle, from development and safety life cycle plans, requirements specifications and design documents, to HAZOPS, the source code, all verification and validation documents and relating evidence. The full test harness, with user and safety manuals, is also supplied.

To access free demos, datasheets and evaluations of SAFERTOS click here.

Medical Design History File

For medical applications SAFERTOS is supplied with a Design History File (DHF). The DHF has been independently validated for compliance with FDA510(k) Class III medical device standards and EN62304. Used in professional and commercial medical applications, such as diabetes pumps, infusion systems and hypertension monitoring systems, SAFERTOS is a comprehensive solution which is specially developed to ease the path to certification. Learn more about SAFERTOS for Medical.

The Contents


The SAFERTOS DAP/DHF contains all the information required to independently complete final product certification.

A typical Design Assurance Pack contains the following documents:

Getting Started
SafeRTOS User Manual

Provides an overview of SAFERTOS and gives a description of the RTOS task, queue and scheduling mechanisms, and provides an API reference.

SafeRTOS Safety Manual

The safety manual contains a concise list of instructions clearly identifying the installation and integration process your engineers should follow when incorporating the RTOS into your development environment.

Upgrading from FreeRTOS to SafeRTOS

FreeRTOS and SAFERTOS share a similar usage model but are not direct drop-in replacements for each other. This document highlights the areas requiring modification when moving an application from FreeRTOS to SAFERTOS.

Using the SafeRTOS Demo

This technical note provides information that is intended to assist in understanding of the RTOS demonstration program for the selected processor. This demonstration program exercises the SAFERTOS kernel functions in order to show the task creation/scheduling and queue communication within an example application.

Configuration
Software Version Description

Contains an inventory of the materials released, their relating checksums and a record of the changes made to this deliverable over its lifetime.

Planning
Software Development Plan

Defines the IEC 61508 SIL 3 compliant development life cycle used in the development of SAFERTOS.

Software Configuration Management Plan

Gives an overview of the configuration management tool, identifies the items under configuration control, and the configuration management rules and working procedures used in the development of this RTOS.

Software Test Plan

Defines the objectives for each Verification and Validation (V&V) phase, and the relating test environment. Defines the complete V&V  schedule.

Software Safety Management Plan

The objective of the Software Safety Management Plan is to adequately justify that SAFERTOS meets its high level safety requirements. This SSMP forms the plan for ensuring that safety is considered throughout the RTOS development programme and is appropriately designed into SAFERTOS.
