Abstract

This specification provides a method and device for upgrading a programmable logic device, the method comprising: obtaining a general upgrade file of a programmable logic device; wherein, the total upgrade file includes a first file check value, each programmable logic device The upgrade file and its file information; calculate the second file verification value according to the upgrade file and its file information, and compare the total upgrade file according to the first file verification value and the second file verification value Perform verification; after the verification is passed, each programmable logic device is upgraded according to the upgrade file and its file information. This solution encapsulates the upgrade files of multiple programmable logic devices into a total upgrade file, and uses the matching verification mechanism for verification, which can avoid the defect of upgrade failure caused by file transmission errors, and can improve the upgrade of device programmable logic devices.

Description

technical field [0001] This description relates to the technical field of computer software, in particular to a method and device for upgrading a programmable logic device. Background technique [0002] Programmable logic devices are widely used in various electronic devices. Taking Complex Programmable Logic Device (CPLD for short) as an example, CPLD is a programmable logic device that can be constructed according to customer needs. PAL (Programmable Array Logic, programmable array logic) devices and GAL (Generic Array Logic, general array logic) devices are developed, which are digital integrated circuits that users can construct logic functions according to their own needs. The basic design method is to use the integrated development software platform to generate corresponding target files by means of schematic diagrams and hardware description languages, and transmit the codes to the target chip through the download cable to realize the designed digital system. In the ...
