SILVerify

SIL verification made simple.

Powerful, accurate SIL verification software for engineers and teams.

SILVerify is ROAK Engineering's SIL verification software for functional safety engineers. It takes the loop data you already hold — sensors, logic solvers, final elements, proof-test intervals and architecture — and works out whether a safety instrumented function actually achieves its target safety integrity level, with the calculation shown rather than hidden.

What it does

  • Builds safety instrumented functions loop by loop, from initiator through logic solver to final element.
  • Calculates PFDavg and PFH against IEC 61508 and IEC 61511 SIL targets, including redundancy and voting arrangements.
  • Tests the effect of proof-test interval, architecture and device choice before the design is committed.
  • Produces verification output you can hand to an assessor as part of the safety case, instead of an untraceable spreadsheet.

Who it's for

Engineers and teams who need SIL verification to be repeatable, reviewable and defensible — typically in nuclear, defence and high-hazard process environments where the numbers will be challenged.
