In this white paper, an alternative analysis method is presented that allows the IP designer to focus on design and diagnostic implementation. This method lets the designer break down IP elements using a systematic recursive approach and associate each element with one of four principles of data processing needed to justify a diagnostic to detect unintended operation and compile into a datapath analysis dataset. This method does not require the IP designer to be trained in functional safety or understand how an IP is applied during functional safety integration by the customers as an in-context design.

This white paper also shows how the datapath analysis dataset is then used by the functional safety professional to create an IP level FMEDA for application by the customer’s system integrator.
