1. A chip detection method, comprising:
providing a chip to be tested, the chip comprising a power pump region, and the power pump region comprising a plurality of power pump structures;
detecting a dim light signal emitted from the power pump region when the chip is in a preset working mode; and
determining whether the dim light signal matches a corresponding power pump working mode in the preset working mode, and when not, confirming that the power pump region has a defect, the power pump working mode comprising a working state of the power pump structures in the power pump region;
wherein the preset working mode comprises a pre-charge working mode; and the detecting a dim light signal emitted from the power pump region when the chip is in a preset working mode comprises:
transmitting a second test signal from a test equipment to the chip, so that the chip is in the pre-charge working mode; and
detecting a second dim light signal emitted from the power pump region when the chip is in the pre-charge working mode.
