About this template
Built from real certification work.
Hardware integrity has to be calculated, not asserted. This Excel workbook ships with live, documented formulas for PFH / PFDavg, safe failure fraction, and architectural constraints — so your reliability engineers can model a safety function, vary the architecture, and read the resulting integrity directly.
