Abstract
A semiconductor device capable of executing fault injection test on a plurality of failure detection mechanism in a short time is provided. The semiconductor devicehas a plurality of hierarchical modules and an error control modulefor controlling errors in the plurality of hierarchical modules. Each hierarchical module has a safety mechanism to detect failures in the functions of the components that make up the hierarchical modules. The error control moduleincludes a status registerconfigured to record data indicative of the status of failure of each hierarchical module, and a fault injection functionthat outputs an error signal to the status registerto perform fault injection test. The error signal is inputted into the safety mechanism via the status register
