Qualified Functional Safety Data Package
Reduce Development Time, System Complexity, and Certification Risk
Industrial automation, transportation, the smart grid, automotive, military and aerospace, and
medical require that machinery and products are highly reliable, safe, and certied for functional
safety. Safety is a central requirement when you develop machinery that must comply with
worldwide established safety standards such as IEC 61508 and ISO 26262.
When you develop a safe product, you need to consider safety as a core system functionality.
Design challenges include:
•Adoptingqualitymanagementstandards,a“safe”designmethodology,andsafetyconcepts
•Accountingforadditionalprojecteort(timeandtechnology),resultinginlongertimetomarket
and higher cost of ownership

Withsuchasafety-focused
architecture for a SIL3
certied application, you can
reduce the total cost of owner-
ship, design footprint, and
power consumption while
meeting the global requirements
for functional safety.

increases the cost signicantly.
IntegratingaSIL3“safe”solutioninapre-qualiedFPGAwithstandardapplicationfunctions
on the main board not only lowers the safety cost footprint, but it also enhances system
exibilityandshortensdevelopmenttime.Itisdesignedwithsafetyasacoresystemfunction-
