Abstract
A method for scan testing a three-dimensional chip, comprising: establishing a scan forest structure for the three-dimensional chip; generating a first test set and a plurality of test periods, and dividing the first test set into a plurality of test subsets; distributing test vectors in the plurality of test subsets into the plurality of test periods; obtaining a current hotspot of the three-dimensional chip; ranking the plurality of test subsets in accordance with an order of temperature rising values from small to large to obtain a test vector strategy; selecting the test subsets corresponding to the temperature rising values less than a temperature threshold from the plurality of test subsets according to the test vector strategy, so as to generate a second test set; and applying the second test set to the scan forest structure, and updating the current hotspot of the three-dimensional chip.
