Abstract
A method of verifying safety in a circuit design, includes, in part, receiving data representative of the circuit design, identifying a first safety mechanism within the circuit design where the safety mechanism is represented by a first module and has an output port defining a first diagnostic point, identifying a multitude of ports of a second module within the circuit design, determining whether at least one port of the second module is associated with a safety concern, performing a backward path tracing from the first diagnostic point to determine if the port falls within a cone of influence of the first safety mechanism, and establishing that a potential fault appearing at the port is detectable at the first diagnostic point if the port is determined to fall within the cone of influence of the first safety mechanism.
