exida.com has released exSILentia safety lifecycle tool, which integrates SILect (safety integrity level selection), SIF SRS (safety instrumented functions safety requirements specification), and SILver (safety integrity level verification) for functional safety standard compliance.
exSILentia lets the user define a project consisting of one or more SIFs. It also manages project documentation with RTF report generation.
Customizable SIL selection options include risk graph, hazard matrix, and frequency-based targets. A SIF SRS template ensures completeness in requirements definition.
exSILentia SILver allows SIF definition and an IEC 61508-approved calculation engine based on the Markov modeling technique.
