Physically aware scan diagnostic logic and power saving circuit insertion

Abstract

Aspects include a computer-implemented method for scan diagnostic logic circuit insertion in a circuit design topology. A method includes evaluating a scan chain of the circuit design topology, the scan chain comprising a plurality of scan latches and a plurality of physical structures, the evaluating including identifying the plurality of physical structures in the scan chain. The method also includes identifying one of the plurality of physical structures as a physical structure of interest, and responsive to the identification of the physical structure of interest, targeting the physical structure of interest, the targeting comprising inserting scan diagnostic logic at a location in the scan chain that is based on a location of the physical structure of interest in the scan chain.
