Problems solved by technology

This method can record information in a targeted manner, but the overhead is too large and the speed is slow, which has a certain impact on the operation of the original system
And when a fatal error occurs in the software, the original information is lost and the problem cannot be located

Abstract

The invention discloses a method and a device for tracing and debugging a system chip of a communication chip, wherein, the system chip of the communication chip comprises a hardware tracking module. The method has the following steps: firstly, the trace and debug data is written and stored in the hardware tracking module, and then output to a track data analysis machine which stores the track and debug data and then analyses and processes the track and debug data to determine the problem of the system. The method and the device collects the data in debugging in batch according to the demand of design, reduces the cost of software of the original system, is more similar to the real system, can automatically sore the very important system time information in the communication system while in the process of recording the track and debug date, help the designer to effectively understand and analyze the integral process of the system by automatic software analysis, determine the problem more rapidly, save workload of the design staff, and improve the work efficiency.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and device for tracking and debugging a system-on-chip communication chip. Background technique [0002] Related chips of current communication systems, including system-side and terminal-side chips, are usually more complex, and are generally designed as SoCs, including both hardware design and software design. [0003] The system of the SoC chip is relatively large, and its design and debugging involve many modules and are relatively complicated. For tracking complex software faults such as software runaway, there are two traditional tracking and debugging methods. One of the methods is to use the ICE debugging tool that comes with the processor to record all instructions for analysis. All the instructions run by the processor are recorded, the amount of information is too large, and the records are not focused. It is useful to analyze the problems in the design of the so...
