“Radiy has developed unique technology that utilizes FPGAs to implement logic solver capabilities,” said Dave Butler, exida evaluating assessor. “Their strong development process ensures the delivery of products that achieve high levels of functional safety.”

The following is from the exida assessment report:

“The audited development process as tailored and implemented for the RPC Radiy FPGA-based Safety Controller (FSC) RadICS development project, complies with the relevant safety management requirements of IEC 61508 SIL 3.

“The assessment of the FMEDA, done to the requirements of IEC 61508, has shown that the FPGA-based Safety Controller (FSC) RadICS can be used in a Low Demand safety related system in a manner where the calculated PFD AVG is within the allowed range for SIL 3 (HFT >= 0) according to table 2 of IEC 61508-1.

“The assessment of the FMEDA, done to the requirements of IEC 61508, has shown that the FPGA-based Safety Controller (FSC) RadICS can be used in a High Demand safety related system in a manor where the calculated PFH is within the allowed range for SIL 3 (HFT >= 0) according to table 3 of IEC 61508-1.

“This means that the FPGA-based Safety Controller (FSC) RadICS is certified for use in de-energize-to-trip SIL 3 applications in Low Demand Mode or High Demand Mode, when properly designed into a Safety Instrumented Function per the requirements in the Safety Manual (including requirements for proof testing, maintenance, hardware architecture constraints, etc.) and when using the versions specified in section 3.1 of this document.”
