Abstract:
1. A method of designing a semiconductor device within a circuit design application of a computer, comprising: determining a design of the semiconductor device to be fabricated at the computer executing the circuit design application; identifying, at the computer, at least a portion of the design of the semiconductor device to be a yield sensitive circuit by comparing said at least the portion of the design of the semiconductor device to previously known yield sensitive circuits; and forming, at the computer, a scan chain by locating a first pair of flip flops into the semiconductor device such that the yield sensitive circuit, identified by comparing said at least the portion of the design of the semiconductor device to previously known yield sensitive circuits, is between the first pair of flip flops to form the scan chain with the yield sensitive circuit within the design of the semiconductor device, the yield sensitive circuit being connected to the first pair of flip flops, wherein the yield sensitive circuit is located between the first pair of flip flops before performing testing and failure analysis of the semiconductor device.
