Abstract

The invention provides an upgrading method and device for a programmable logic device. The method comprises the steps that a total upgrading file of the programmable logic device is acquired; Whereinthe total upgrade file comprises a first file check value, upgrade files of the programmable logic devices and file information of the upgrade files; Calculating a second file verification value according to the upgrade file and the file information thereof, and verifying the total upgrade file according to the first file verification value and the second file verification value; And after the verification is passed, upgrading each programmable logic device according to the upgrading file and the file information thereof. According to the scheme, the upgrading files of the programmable logic devices are packaged into a total upgrading file, verification is carried out through a matching verification mechanism, the defect that upgrading fails due to file transmission errors can be avoided,and upgrading of the programmable logic devices of equipment can be improved.

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 ...
