Auxiliary communication device for embedded equipment testing

Abstract

The invention discloses an auxiliary communication device for embedded equipment testing. The auxiliary communication device comprises a general logic processing module and a special physical interface module. The general logic processing module comprises an FPGA chip and an Ethernet interface chip / component, and the Ethernet interface chip / component is used for realizing data transmission betweentest equipment and an FPGA according to an Ethernet protocol. A corresponding embedded bus logic processing IP core is deployed in the FPGA as required to finish conversion between bus data used by embedded equipment and Ethernet data. The special physical interface module is used for providing a corresponding interface according to a bus used by the embedded equipment so as to enable the auxiliary communication device to be interconnected and communicated with the embedded equipment according to the electrical interface specification requirements. According to the invention, the device can independently operate without depending on test equipment, and the flexibility and efficiency of deployment are improved.

Description

technical field [0001] The invention relates to a communication board technology, in particular to an auxiliary communication device for embedded equipment testing, which is used to solve the data communication between the testing equipment and the tested embedded equipment. Background technique [0002] In the test and verification environment of embedded devices, the test equipment usually uses a communication board to realize data communication with the embedded device under test. Due to the variety of embedded devices, huge differences in software and hardware, and the use of various data communication buses, traditional communication boards have the following shortcomings: [0003] First of all, the hardware design of traditional communication boards usually uses dedicated chips for specific buses, and the hardware design of different types of boards varies greatly. Due to the specificity of this software and hardware, the traditional communication board has a single f...
