Embodiment Construction

[0040] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] refer to figure 1 , which shows a flow chart of Embodiment 1 of a fast chip verification method for multimedia playback in the present invention, including:

[0042] Step 101, randomly read the file to be tested from the memory;

[0043] Various files to be tested are stored in the memory, and the memory can be a storage device such as an SD card. This step randomly reads the files from the memory, which includes image and video files in multiple formats, so as to ensure that it can be used for each This file is used for comprehensive chip verification.

[0044] The files can be divided into four categories: JPEG images, YUV images, RGB images and video files. Among them, various files can be further subdivided, such as ...

Abstract

The invention provides a method and device for rapidly verifying a chip by multimedia player. The method comprises the following steps: reading a file to be tested from a memory; judging the type of the file and automatically carrying out constraint correction on attribute parameters of the file when the file is a YUV image or an RGB image; when the file is an JPEG image or a video file, carryingout constraint correction on the attribute parameters of the file after decoding the file; setting up corresponding attribute parameters according to the constraint correction result, and inputting the file into a tested module provided with a verification chip to play; and circularly carrying out each testing step and traversing the testing of each file in the memory. By the invention, the imagefiles and the video files are automatically traversed and played so as to simplify the operation of the tester, save the human resources, improve the working efficiency and rapidly verifying the stability of the chip.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to a fast chip verification method and device for multimedia playback. Background technique [0002] The rapid development of semiconductor technology has promoted the increase of chip integration and performance, which not only increases the difficulty of chip design, but also increases the cost of post-testing of chips. In order to verify whether the performance of the finished chip is consistent with the design expectation, it is necessary for the test equipment to provide testing capabilities to test the performance parameters of the chip during actual operation. [0003] Verification testing is the key to achieving a seamless connection from design to test. In the manufacturing process below 0.18 micron, the chip verification test becomes more critical. Its main task is to verify the correctness of the design and test procedures to determine whether the chip meets all design...
