Our range of Safety Components extend the functionality of SAFERTOS to address specific customer requirements
Bristol, UK (PRWEB UK) 23 August 2016
WITTENSTEIN high integrity systems presents Checkpoints, a software Safety Component that extends the functionality of the safety critical Real Time Operating System SAFERTOS. Checkpoints provides a sophisticated Task monitoring capability that confirms the correct scheduling of Tasks within a pre-emptive, priority based scheduling environment.
The Checkpoints Safety Component has been designed to meet the Automotive ISO 26262 ASILC/D requirement which mandates the self-monitoring of the software in the operating system and the application. ISO 26262 mandates the use of self-monitoring to detect, identify and manage systematic faults. Both Checkpoints and SAFERTOS are supplied with a Design Assurance Pack supporting certification to ISO 26262 ASIL D.
Checkpoints allows the user to specify timing tolerances for critical sections of code. This can be used to confirm that periodic Tasks run within allowable tolerances and that sections of processing within Tasks complete within a defined time period. Checkpoints can monitor the time between an Interrupt event happening and the completion of the relevant handler Task. Checkpoints can also monitor complex functionality involving multiple Tasks, confirming timing constraints are met. If timing constraints are violated, an error hook is triggered.
