Abstract

The invention provides a network-on-chip test method and device. The method comprises the steps that a test data packet is generated and the test data packet is backed up; the test data packet is transmitted in a network-on-chip to be tested according to a preset first transmission path; when the test data packet is transmitted to the terminal node of the first transmission path, a second transmission path is generated, wherein the terminal node of the second transmission path is the start node of the first transmission path; a reorganized data packet is generated according to the test data packet received at the terminal node of the first transmission path; the reorganized data packet is transmitted in the network-on-chip to be tested according to the second transmission path; and when the reorganized data packet is transmitted to the terminal node of the second transmission path, a test result is generated according to the reorganized data packet received at the terminal node of the second transmission path and the backup test data packet. According to the network-on-chip test method and device, testing of the network-on-chip can be realized.

Description

technical field [0001] The invention relates to the field of chip design, in particular to an on-chip network testing method and device. Background technique [0002] An on-chip network composed of multiple nodes is generally arranged in the chip. The network on chip is an important part of the chip to complete the transmission of data packets between nodes. The network on chip has complex data paths and control logic. [0003] During chip development and other processes, in order to determine whether the on-chip network of the chip works normally, it is necessary to test the on-chip network of the chip. Currently, there are no plans to test a network-on-chip. Contents of the invention [0004] Embodiments of the present invention provide a method and device for testing a network on chip, which can realize testing the network on chip. [0005] In a first aspect, an embodiment of the present invention provides a method for testing a network on chip, including: [0006] ...
