Problems solved by technology

[0005] However, the XML file is in the form of plain text in the VTR, and all description information is stored in the same XML file, which is inconvenient for subsequent upgrades to the FPGA architecture and may leak internal details of the FPGA resource structure.

Embodiment 1

[0020] A kind of storage method described for the FPGA structure of this embodiment, such as figure 1 As shown, perform the following steps:

[0021] 1) Use the XML file to describe the structure information of the FPGA;

[0022] Describe the structure information of FPGA with several XML-based tag files;

[0023] 2) Modularize the XML file;

[0024] Save all the original content in one file and upgrade to split the file according to modules, for example, use The primitives to be described are placed in different files. When describing the FPGA resource structure of other versions later, the same primitives can be reused, and it is also convenient for subsequent upgrades and maintenance;

[0025] 3) Parse the XML file and process the data in it to conform to the rules and constraints of the SQLite database;

[0026] 4) Use a database for storage;

[0027] Call the interface to write data into the SQLite database, use the FPGA version number and the label ...

Abstract

The invention relates to a storage method for FPGA structure description, and belongs to the technical field of data processing. The method comprises the following steps of: 1) describing the structure information of the FPGA by using a plurality of label files based on XML (Extensible Markup Language); 2) modularizing the XML file; 3) analyzing the XML file, and processing data in the XML file to enable the data to accord with rule constraints of the SQLite database; according to the method, the XML file content is subjected to encryption protection, the plaintext leakage condition is effectively eradicated, meanwhile, developers can rapidly know the internal architecture details of the FPGA, later architecture maintenance and upgrading are facilitated, and the development efficiency is improved.

Description

technical field [0001] The invention relates to a storage method for FPGA structure description, belonging to the technical field of data processing. Background technique [0002] Field Programmable Gate Array is the product of further development on the basis of programmable devices such as PAL and GAL. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of original programmable device gates. [0003] With the increasing integration of chips, it has become unrealistic to use traditional manual wiring methods on highly integrated circuits. Therefore, EDA tools are becoming more and more important in the design of integrated circuits. As a substitute chip for general-purpose processors, FPGA is more and more widely used in high-tech fields such as high concurrency, image processing, and large-scale data processi...
