Abstract

The embodiment of the invention provides a chip mac layer verification system and method, and the system comprises the steps: a receiving side of a to-be-detected mac layer is used for receiving a first data packet sent by a receiving side of a pause frame sender, and changing the sending information of the sending message information of a target interface of a sending side of the to-be-detected mac layer based on the first data packet; the receiving side of the pause frame capturing device is used for capturing frame information of a first pause frame and sending information of a target interface of the sending side of the mac layer to be detected; and the verification device is used for verifying the receiving side of the to-be-detected mac layer based on the frame information and the sending information of the target interface of the sending side of the to-be-detected mac layer. Through the mode, the verification accuracy of the mac layer of the chip is improved.

Description

technical field [0001] The present invention relates to the technical field of chip verification, and in particular, to a chip mac layer verification system and method. Background technique [0002] In the mac layer of the Ethernet, in addition to sending and receiving general message information, it also needs to send and receive pause frames according to the IEEE802.3 protocol standard. The mac layer of the Ethernet makes corresponding behavioral responses based on the sent and received pause frames. [0003] At present, the verification method for the mac layer of the chip is only to send a pause frame to the mac layer, and obtain the response results of the receiving side and the transmitting side of the mac layer to the received pause frame, and verify the mac layer based on the response results. [0004] The verification of the mac layer in the above method will lack the coverage of the coupling situation such as the combination of the pause frame and various other mes...
