Chip debugging method and device

Abstract

The present invention discloses a method and device for debugging a chip. The method includes the following steps: connecting to a communication interface of an information processing device, obtaining debugging configuration information from the information processing device; collecting sampling signals from the debugging chip according to the debugging configuration information; The signal is output to an information processing device. Therefore, by using the existing information processing equipment to set the debugging configuration information, according to the debugging configuration information, the sampling signal is collected from the debugging chip and then output to the information processing equipment, and then the information processing equipment is used to perform logical analysis on the debugging chip according to the sampling signal The processing and debugging operations make full use of the functions of the existing equipment, which greatly reduces the cost and realizes low cost. Moreover, the user can conveniently and intuitively set the debugging configuration information and perform logic analysis processing and debugging operations on the debugging chip on the information processing device, so the operation is convenient and fast, and the functions are rich enough.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a chip debugging method and device. Background technique [0002] After the digital logic is processed and produced into a chip, it is very difficult to trace the internal logic behavior. Because after the chip is packaged, usually only its external pins can be detected, and all its internal logic and state behavior are invisible. However, the most important and primary task of chip prototyping is to check the functional integrity of the chip. Once the chip behavior is found to be inconsistent with the simulation or expectations during the test, it is necessary to track and debug the internal logic and state to locate and find the problem. . [0003] At present, the common practice of chip debugging is to assign important internal registers, state machine states, and some control signals and data signals to the external pins of the chip through a series of grouping and mult...
