Digital signal logic analyzing system

Abstract

The invention relates to a digital signal logic analyzing system. The digital signal logic analyzing system comprises a digital communication transceiver, a protocol analyzing module, a user display module, a storage module and a protocol description document download module, wherein the digital communication transceiver is used for receiving and dispatching data in a mode of byte stream through at least one interface of at least one digital communication protocol; the storage module is used for storing a protocol description document of the digital communication protocol; the protocol analyzing module is used for receiving the byte stream from the digital communication transceiver, and analyzing the byte stream into structuralized data of a specific data structure according to the protocol description document; and the user display module is used for displaying the structuralized data in preset formats dynamically according to the protocol description document. Consequently, an integrated test simulation tool which is reliable, flexible and extremely expansive is provided for integration, maintenance and evaluation personnel of the system.

Description

technical field [0001] The invention relates to analysis and testing of digital signals, in particular to a digital signal logic analysis system for performing protocol analysis and simulation testing on digital signals based on protocol description documents. Background technique [0002] Existing digital signal analysis is mainly carried out by a logic analyzer, which can usually follow the communication protocol from SPI (Serial Peripheral Interface, Serial Peripheral Interface), I2C (Inter-Integrated Circuit, internal integrated circuit), UART (Universal Asynchronous Receiver / Transmitter, CAN, parallel interface, USB (Universal Serial BUS, universal serial bus) and other buses record the byte data of communication and change in characters, values, or levels form to display. However, the data transmitted on the bus is often structured data packaged according to a certain format, and the logic analyzer often cannot analyze the structure of the data packet from the byte st...

AI Technical Summary

Problems solved by technology

[0008] Commonly used analysis tools include logic analyzers and protocol analyzers, which mainly solve the analysis problem of the underlying data communication, and cannot capture the data model contained in the byte stream, nor have the data sending function, and cannot be used to debug application layer communication semantic logic

[0009] If you do not use a logic analyzer, you must build a corresponding hardware platform, prolong the development, evaluation, and verification cycle, increase costs, and lack a standard evaluation test environment
