The application provides a 2D structure chiplet test layout design method. The method uses a hexagonal arrangement for each test point, and uses a test PIN to connect six signal pins to reduce the signal lead-out end. The test circuit with switching function is designed to realize independent control of each test PIN. The test process is designed according to the control signal of the test circuit to realize single chiplet self-test and cascade test, thereby judging the signal connectivity. Under this design method, the test PIN and the adjacent signal PIN are arranged at equal distances, the single test PIN is controlled, the test can be performed one by one, and the cascade test is performed after the single chiplet self-test, so as to improve the test efficiency and accuracy. In addition, the chiplet layout is arranged in a hexagonal manner, the signal pin coverage is improved, the number of test PINs is reduced, and the signal transmission efficiency under the same area is improved.
