Embodiment 1

[0041] refer to figure 1 , showing Embodiment 1 of a simulator-based processor fault injection and tracking method of the present invention, including the following steps:

[0042] Step 101, abstract the processor into a simulator with simulation modules.

[0043] First, a software simulator that simulates the processor structure can be developed according to the specific processor structure, and the processor structure can be abstracted into an analog module of the software simulator. Specifically, the structure and code of the software simulator can be analyzed according to the technical data of the processor, and the corresponding relationship between each functional part of the processor and the simulation module in the software simulator can be determined, thereby abstracting the processor structure into a simulation module. For example, in general, the processor structure can be abstracted into analog modules such as register modules, memory modules, execution modules, ...

Abstract

The invention provides a simulator-based processor fault injection and tracking method, comprising the following steps: abstracting the processor into a simulator with simulation modules; simulating various faults in each simulation module of the simulator and performing Fault source and fault command marking; fault transmission tracking, identification of fault source and fault command. The simulator-based processor fault injection and tracking method of the present invention can track the fault triggering and transmission process, and extract the information of components and instructions that realize the fault, so as to conduct comprehensive analysis on the fault. The present invention also provides a simulator for implementing the aforementioned simulator-based processor fault injection and tracking method.

Description

technical field [0001] The invention relates to computer processor technology, in particular to a simulator-based processor fault injection and tracking method and the processor simulator. Background technique [0002] With the advancement of integrated circuit technology, the integration of key components of computer systems such as processors and memory is getting higher and higher. While bringing about rapid performance improvements, a key issue that follows is the reliability of highly integrated components. Performance will be reduced, and if fault tolerance measures are not taken, the overall availability of the computer system may be impaired. In order to improve reliability, some fault-tolerant technologies are widely used in modern processors, such as ECC (Error Correcting Code, error checking and correction) / DCC (Document Control Center, file control center) technology, checkpoint technology, component redundancy technology, address error detection techniques, etc...
