A method is provided for validating measurement data, such as data obtained from a scanning electron microscope using in a semiconductor fabrication facility. The method includes applying a signal on a material feature by using a source in a measurement tool having a tool setting parameter, collecting a response signal from the material feature by using a detector in the measurement tool to obtain the measurement data, calculating a simulated response signal by a smart, and validating the measurement data by comparing the collected response signal with the simulated response signal. The system also includes a design database having a design feature, a measurement tool collecting a response signal, and a smart review engine configured to connect the measurement tool and the design database. The smart engine generates a simulated response signal using the design feature and a measurement tool setting parameter so that the measurement is validated by comparing a collected response signal and a simulated response signal.
