Chip wireless debugging circuit and method

Abstract

The invention provides a wireless debugging circuit and method for a chip, and the circuit comprises a chip internal circuit and a debug demodulation circuit. The chip internal circuit comprises a plurality of CPUs, a plurality of CPU monitors, a plurality of information packaging units, an information merging unit, a chip end NFC control unit, a chip end NFC communication field unit, and a time stamp controller. The debug demodulation circuit comprises a demodulation end NFC communication field unit, a demodulation end NFC control unit, a debug information splitting unit, a plurality of information unpacking units, and a plurality of CPU debug information pools. The circuit can complete the communication connection in the whole debugging process only if the NFC communication field of the debug demodulation circuit gets close to the NFC communication field of the chip, and there is no need of a physical electrical interface of the chip for wiring.

Description

technical field [0001] The invention relates to a chip wireless debugging circuit and method. Background technique [0002] With the rapid development of SOC chip technology, the Internet of Things technology is becoming more and more important. However, an important problem currently restricting IoT chip devices is that all devices and basic chips still rely on traditional physical electrical devices, such as power sockets, debugging sockets, etc. Work in liquid environments such as swimming or bathing or other harsh environments. However, with the development of technology, there have been some chips that do not require physical connection, but the verification and testing of these chips has become a difficult problem. [0003] Therefore, the present invention proposes a debugging circuit and method, which can debug the chip without physical connection, which greatly supports and improves the production and development process of chips without physical electrical interfa...

However, an important problem currently restricting IoT chip devices is that all devices and basic chips still rely on traditional physical electrical devices, such as power sockets, debugging sockets, etc. Work in liquid environments such as swimming or bathing or other harsh environments

However, with the development of technology, some chips that do not require physical connection have appeared, but the verification and testing of these chips has become a difficult problem

[0003] Therefore, the present invention proposes a debugging circuit and method, which can debug the chip without physical connection, which greatly supports and improves the production and development process of chips without physical electrical interfaces. At the same time, if the debugging circuit or method Used on traditional chips, it can also simplify the complexity of test equipment design, and can also solve the vulnerability problem of physical connection equipment
