Description

Technical Field

[0001] The present invention relates to the technical field of embedded devices, and more specifically, it relates to a multi-functional emulator. Background Art

[0002] At present in the market, main chips of different manufacturers are equipped with their respective dedicated emulators for debugging different main chips. For example, when debugging an FPGA, the emulator of Xilinx is required, as Figure 1 shown. When debugging an MCU, devices such as J-LINK and ST-LINK are required. When debugging a CPU, an Ethernet port and a serial port are usually used. In addition, a dedicated SPIFLASH programmer is required when burning a boot file, and so on. During the development process of military complex electronic products, it is often necessary to use multiple chips such as CPU, FPGA, MCU, and SPIFLASH simultaneously. This requires carrying multiple different emulators, which will bring great trouble to those who travel on business. On the one hand, a laptop usually has only a limited number of USB interfaces and may not have an available RS232 debugging serial port. On the other hand, there are many inconveniences in carrying multiple emulators. Summary of the Invention

When in use, the target interface is used to connect the product to be debugged corresponding to the interface, realizing the interaction between the target interface and the product to be debugged while realizing the interaction between the debugging terminal and the product to be debugged, and finally achieving the purpose of simulating and debugging the product through the debugging terminal.

[0007] In this solution, by connecting multiple interface conversion chips to the same interface expansion chip, there is no need to carry multiple different emulators during actual use, reducing the trouble brought by carrying. At the same time, the interface expansion chip is used to expand the USB interface of the debugging terminal, thus avoiding the situation of insufficient USB interfaces.
