Techniques are presented for reliability analysis of integrated circuits. A circuit data file including a connectivity network with appended parasitic information is obtained. Circuit performance is simulated, based on the data file, to obtain simulated currents for metallic conductive paths of the circuit. Contextual representations of the paths are determined, and reliability analysis is performed on the contextual representations. The analysis can relate, for example, to electromigration, joule-heating, and/or fusing. The results of the analysis can be provided, for example, in the form of a report including recommended changes, such as width increases, to wires for which it is determined that reliability issues exist.
