Claim of US Patent No. 10,169,510

1. A computer implemented method for locating defects in a fabricated device, the method comprising:inputting, by a computer system, inline fabrication parametric data, the inline fabrication parametric data is a collection of physical measurements measured on the fabricated device during stages of building process layers in the fabricated device, wherein a fault model is based on the inline fabrication parametric data;
generating, by the computer system, test patterns according to inline fabrication parametric data of the fabricated device according to the fault model in order to obtain results from testing the fabricated device; and
detecting a physical location of one or more defects in the fabricated device by running a simulation of the fabricated device using the results.
