Video data reception system verification method and apparatus thereof

Abstract

The invention relates to a circuit verification apparatus, and discloses a video data reception system verification method and an apparatus thereof. In the invention, according to a verification requirement, a video data to be tested reception system is subjected to random configuration, and according to configuration information, with constraint of a related video protocol, test data is generated automatically. The video data to be tested reception system and a verification model carry out parsing and transmission processing on the test data respectively, and through comparing processing result data of the system and the model, a verification result of a video data reception system is obtained. Thus realization of verification of the video data reception system is facilitated, artificial intervention of verification personnel is minimized, and a high verification coverage rate is easy to realize.

Description

technical field [0001] The invention relates to a circuit verification device, in particular to an automatic verification technology of a video data receiving system. Background technique [0002] In recent years, video data receiving systems have been widely used in various logic chips. With the increasing number of video formats supported by the chip system, the processing of video data is becoming more and more complicated, and it has become more and more important to perform reliable and efficient verification of the video data receiving system in the circuit design stage. [0003] At present, a conventional verification device for a video data receiving system such as figure 1 shown, figure 1 The external video data sources in are selected by the verifier according to the test procedures corresponding to different test cases. The video data receiving system to be tested (that is, the video data receiving system that needs to be verified, typically consists of a data ...

AI Technical Summary

Problems solved by technology

[0005] (1) The efficiency is not high: the entire verification process is not fully automated, and more manual intervention is required (for example, verification personnel are required to switch external video data sources and select data processing reference models according to different test cases, and use a text comparator to compare the result data to compare, etc.)

[0006] (2) Difficulty in debugging: it is difficult to accurately locate the defect after the circuit defect is found (typically, it is difficult to determine whether the defect occurs in the data analysis module or the data transmission module according to the data comparison result)

[0007] (3) It is not easy to achieve high verification coverage: because the above-mentioned verification device is to generate all test cases by the verification personnel, and then verify according to the given test cases, if it is necessary to check all possible video data sources and the working mode of the system under test For more comprehensive coverage, verifiers are required to manually generate many test cases, which will cost a lot
