Problems solved by technology

[0014] Since the CRC32 verification method requires the input and output terminals of the logic device to perform CRC32 algorithm processing bit by bit, due to the complexity of the CRC32 algorithm processing, the implementation workload is relatively large. Section) data errors can be completely detected, but for data errors larger than 32 bits (4 bytes) in data transmission, it cannot be completely detected

Abstract

The invention discloses a method and apparatus for proving message net load transparent transmission logic, comprising: generating each net load value of the input message of logic equipments' input port according to the pre-defined algorithm; verifying each net load value of output message of logic equipment' output port according to the pre-defined algorithm, if each net load value of the output message fits the pre-defined algorithm, then pass the verification, otherwise the said logic equipments have logic errors. The said apparatus mainly comprise logic verification message generating unit and logic verification unit. The invention is characterized in that only need to make pre-defined algorithm processing on the input data of the logic equipments and verify if each net load value of output message fits the pre-defined algorithm of the output message to judge the correctness of the logic.

Description

technical field [0001] The invention relates to the technical field of communication testing, in particular to a method and device for verifying message payload transparent transmission logic applied in large-scale logic chips. Background technique [0002] Destination address (6 bytes) source address (6 bytes) type (2 bytes) data (46~1500 bytes) CRC (4 bytes) [0003] Wherein, the destination address, source address and type field are the header of the message, the data field is the payload, the length of the payload is variable, and the CRC is the tail of the message. [0004] The logic chip is a chip designed to realize specific logic functions. For example, many large-scale logic chips are used in switching services to realize switching logic functions. Many existing large-scale logic chips directly forward the payload part of the transmitted message, that is, the logic chip transparently transmits the message pay...
