FPGA external memory verification method and device

Abstract

The embodiment of the invention provides a calibration method and device for a FPGA plug-in storage. The method includes the following steps that an FPGA obtains first data and a first address corresponding to the first data, wherein the first data and the first address are written into the FPGA plug-in storage; a first address to be calibrated with the same digit with the first data is obtained according to the first address; XOR is performed on the first data and the first address to be calibrated, and a first XOR result is obtained; XOR is performed on the first XOR result and an initial calibration value, and a first calibration value is obtained. According to the calibration method and device for the FPGA plug-in storage, XOR is performed on the first data and the first address to be verified, XOR is performed on the XOR result and the initial calibration value, the calibration value is obtained, mixed calibration of the address and the data written into the FPGA plug-in storage is achieved, calibration of the data is finished, calibration of the address is also finished, and errors of the address can be found in time.

Description

technical field [0001] The invention relates to communication technology, in particular to an FPGA external memory verification method and device. Background technique [0002] At present, the capacity of Field Programmable Gate Array (Field Programmable Gate Array, FPGA for short) chips is getting larger and larger, and the functions completed are getting stronger and stronger. In addition, as the scale of external memory becomes larger and larger, the failure probability of external memory is also increasing, and the failure of external memory has an increasingly serious impact on the functions of the above-mentioned FPGA. With the development of large-scale FPGA, more and more applications Start to pay attention to the application reliability of FPGA's external memory. [0003] In the prior art, the verification method of the external memory of the FPGA is mainly to verify the data of the external memory. Specifically, it can be based on the start address, end address an...
