AI Technical Summary

Problems solved by technology

However, not only are protocol analyzers expensive, but the data verifiable by developers is also inelastic
Protocol analyzers may also be limited in use as the specification of the interface transport protocol changes
Furthermore, when the chip has been set on the circuit board and becomes a commodity, it is difficult to connect it to a logic analyzer for analysis.

Embodiment Construction

[0045] Compared with using expensive analytical instruments for interface transmission testing, the present invention completes the interface transmission testing by extracting packet transmission information by the data transmission circuit itself. In order to make the content of the present invention clearer, the following examples are listed as examples in which the present invention can actually be implemented.

[0046] figure 2 It is a schematic structural diagram of a packet data analysis system according to an embodiment of the present invention. Please refer to figure 2 , the packet data analysis system 200 includes a chip under test 210 , a data receiving circuit 220 , a storage unit 230 and an external device 240 . The chip under test 210 is connected to the data receiving circuit 220 through the transmission interface I1. The transmission interface I1 is an inter-chip connection interface supporting an interface transmission protocol. For example, the interfac...

Abstract

The invention provides a packet data analysis method and a packet data analysis system. A data receiving circuit receives at least a packet based on an interface transmission protocol. A data receiving circuit extracts packet transmission information of the packet and stores the packet transmission information in a storing unit. An external device is connected with the storing unit to obtain a specific format file generated based on the packet transmission information. The external device opens the specific format file so as to display the packet transmission information. Therefore, by receiving the packet and extracting the packet transmission information through a data transmission circuit automatically, packet data transmitted through a packet serial interface can be analyzed and detected without an expensive analysis instrument.

Description

technical field [0001] The present invention relates to a data analysis method of a transmission interface, and in particular to a packet data analysis method and a packet data analysis system. Background technique [0002] Generally speaking, for a serial packet transmission interface with a specific specification, the interface transmitter must packetize data into multiple packets according to a specific packet format, so as to transmit these packets through the serial packet transmission interface. When the research and development personnel want to detect the packet data transmitted by the chip under test through the serial packet transmission interface, they usually use an analysis instrument to extract the digital signal input to the chip under test or output from the chip under test. In this way, the research and development personnel can analyze and detect whether the above-mentioned extracted digital signal is normal according to the content of the signal displayed ...
