IEC 61508 Functional Safety Readiness With FPGAs

We are committed to providing you with FPGAs that you can successfully use in safety-critical designs. New technology brings new ways for a system containing electronics or programmable electronics to fail. Failures can cause harm to people and property and although it is impossible to guarantee a technological system will never fail, it is possible to reduce the risk of failure and to design systems so that if they do fail, they fail safely.

IEC 61508 Compliance

IEC 61508 requirements are extensive. They ensure that functional safety is considered and accounted for in all aspects of the program for the entire lifecycle of the product. The image below illustrates the overall lifecycle required by the IEC61508. The depth and rigor of the requirements depend on the Safety Integrity Level (SIL) of the safety-related functions involved.

V-Model Development 

Most often, FPGAs are components in a much more complicated system. IEC 61508 requires the use of a V-model for development that describes the sequence of verification and validation activities. Our V-model is shown below:                        

Timeline Reduction for Functional Safety 

We provide a complete ecosystem based on robust design flows that includes supporting documentation, IPs, certification and more to minimize risks for customers and reduce time to market.
