Embodiment Construction

[0024] Such as figure 1 As shown, the knowledge base-based FPGA fault automatic diagnosis method of the present invention includes the following steps:

[0025] 1. Obtain FPGA fault information through data mining, manual collection and other methods, and format the fault information into a unified format, including the occurrence process of the fault (design, simulation verification, etc.), and the performance status of the fault (chip model, input and output, waveform Figures, etc.), fault solutions, etc., as the information source of the fault knowledge base to establish the fault knowledge base.

[0026] The existing FPGA fault resolution technical solutions are generally solved by asking professionals and through personal experience. Personal experience is not only difficult to acquire, and the stock of knowledge is small, but there are also problems of inaccuracy or even inaccuracy. The fault knowledge base established specifically includes the following:

[0027] a. Device s...

Abstract

The invention discloses an FPGA (filed programmable gate array) fault automatic diagnosing method based on a knowledge database. The method includes: structuralizing fault information during storage FPGA design and verification; performing fault search according to feature information a new fault case, matching most related and similar fault information according to information such as fault generation and fault feature, and displaying detailed contents and fault solutions to solve the new fault. Acquired fault experience and methods during FPGA design verification are used to build a knowledge database system, detailed fault information and solutions are displayed visually, faults can be positioned accurately, conveniently and fast, and fault debugging and solving efficiency of FPGA design verification staff is increased greatly.

Description

Technical field [0001] The invention relates to a knowledge base-based FPGA fault automatic diagnosis method, in particular to a knowledge base-based FPGA fault automatic diagnosis method that uses formatted FPGA fault knowledge and uses a similarity detection method to automatically match all possible fault information for users diagnosis method. Background technique [0002] Field Programmable Gate Array (FieldProgrammableGateArray) is a kind of field programmable ASIC. As a new type of programmable device that combines the general structure of gate array with the field programmable features of programmable logic devices, FPGA has many advantages, Developed very rapidly. But with the continuous expansion of FPGA scale and integration, FPGA product designers and verification personnel, especially inexperienced personnel, are particularly prone to make mistakes in the development process. In view of the difference between the FPGA design process and ordinary software development...
