Claim:
1. A method for performing a semiconductor parametric test at a test engine, comprising: performing a full voltage sweep for a first component on a first semiconductor wafer to determine a first value of an electrical characterization parameter for the first component, wherein the full voltage sweep comprises a range between about a minimum input voltage level of the first component and about a pre-determined stop voltage level of the first component; determining a smart sensing window (SSW) for a plurality of subsequent components on the first semiconductor wafer according to the first value, wherein the SSW comprises a range comprising a portion of the full voltage sweep range; performing a partial voltage sweep in the SSW for each of the subsequent components to determine a second value of the electrical characterization parameter for each of the subsequent semiconductor components; and adapting the SSW for at least some of the subsequent components.
