Functional testing: Functional testing is the most basic chip testing method used to verify whether the chip is working properly according to design requirements. Perform functional testing by inputting specific input signals and checking if the output meets expectations.


Timing test: Timing test is used to verify whether the timing relationship between various components inside the chip is correct, to ensure that the data reaches the target position at the correct time.


Power consumption testing: Power consumption testing is used to measure the power consumption of a chip under different operating conditions, in order to evaluate the energy efficiency and power management performance of the chip.


Temperature testing: Temperature testing is used to evaluate the performance of a chip under different temperature conditions, to ensure that the chip can function properly in various environments.


Boundary scan testing: Boundary scan testing is a structured testing method used to detect the connectivity and status of chip boundaries to ensure correct chip connections.


Fault mode analysis: Fault mode analysis is used to evaluate the performance of a chip under different fault conditions, to ensure that the chip can handle abnormal situations correctly.


Production testing: In the process of mass production of chips, large-scale production testing is also required to ensure that each chip meets specifications and can function properly.


Chip testing requires the use of specialized testing equipment and software tools to ensure the accuracy and efficiency of testing. Through a comprehensive testing process, the quality and reliability of the chip can be ensured, thereby improving the performance and reliability of the final product.
