[0003] In existing test cases, the generation of background noise is often relatively independent of the current operating state of the chip, and the generation of background noise will not adapt to the current operating state of the chip, which may result in two extreme situations: (1) the chip It is not running, but the background noise keeps happening, that is, meaningless noise is generated; (2) the chip is still running, but the background noise stops happening, and the test pressure seems insufficient in this case

Embodiment Construction
[0019] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.
[0020] Embodiment 1 of the present invention provides a chip verification method. In the chip verification module, the verification method can be run every once in a while, such as figure 1 shown, including the following steps:
[0021] Step 101: Obtain the running state of the chip; here, when the signal used to indicate that the chip is running is obtained, it means that the running state of the chip is running, otherwise, it means that the running state of the chip is stopped.
[0022] Step 102: When it is determined that the operating state satisfies a preset condition, perform read and write operations on the ...

The invention provides a chip verification method and device. The verification method comprises the following steps: obtaining the running state of the chip; when it is determined that the running state satisfies the preset condition, performing reading and writing operation on the register and / or the table entry, and verifying the chip functionally. In the verification method, it is determined whether to read and write the registers and / or entries according to the operation state of the chip, that is, whether to read and write the registers and / or entries is related to the operation state ofthe chip, so that meaningless background noise can be avoided, or a sufficient amount of background noise cannot be generated.
Description
technical field [0001] The invention relates to the technical field of chip verification, in particular to a chip verification method and device. Background technique [0002] In the prior art, during the operation of the chip, related configurations are often required; for example, in a high-bandwidth network chip, it is necessary to read and write the registers and entries in the message processing process, these are Background noise during normal chip operation. It can be understood that during the chip verification process, the following verification needs to be performed: read and write registers and / or table items, and during this process, it needs to verify that reading and writing does not affect the normal function of the chip. [0003] In existing test cases, the generation of background noise is often relatively independent of the current operating state of the chip, and the generation of background noise will not adapt to the current operating state of the chip,...
