Abstract
A method for determining system reliability of a logic circuit, wherein a functional component model for design/simulation of a circuit model of the logic circuit is created, where functional components model are expanded by adding an associated power model, a temperature model, and a reliability, where the logic circuit is constructed with expanded model components and, based on simulation of the logic circuit aided by the constructed circuit model, a functional, a power-dependent, and a temperature-dependent behavior and a temperature-dependent failure rate are derived for each component in a component specific manner for a specified application case, and where in addition to the functional behavior, a power and temperature behavior and a total failure rate can be determined simply and dynamically, based on the derived data and dependent on temperature and simulation time for the logic circuit for the specified application case.
