Abstract
A chip, a chip testing method and an electronic device are provided. The chip includes a combinational logic and a data path gating; the data path gating includes a first input terminal and an output terminal, the first input terminal of the data path gating detects a test enable signal, and the output terminal of the data path gating is connected to the combinational logic; the test enable signal is used to switch a test mode of the chip; the data path gating is configured to output a data path gating control signal to the combinational logic, in a case where the detected test enable signal indicates that a current test mode is irrelevant to a data path function of the combinational logic; and the combinational logic is configured to disable the data path function after receiving the data path gating control signal, to disable data path toggling.
