Abstract

The invention provides a signal acquisition method and a chip verification platform. The method comprises the following steps: when an exception occurs in a process of running a bit stream file of a to-be-tested design of a chip, recording a time point when the exception occurs by utilizing a clock counting module in the bit stream file; in the abnormal debugging process, a clock control module is used for controlling the to-be-tested design to run in a first running time period, and the right side endpoint value of the first running time period is not larger than the time point; when the running duration of the to-be-tested design reaches the first running time period, controlling the to-be-tested design to run in a second running time period; and in the operation process of the to-be-tested design in the second operation time period, the clock control module is utilized to control the signal acquisition module to acquire signals needing to be observed in the abnormal debugging process according to a single-cycle mode.

Description

technical field [0001] The present application relates to the technical field of chip design, in particular to a signal acquisition method and a chip verification platform. Background technique [0002] When verification is performed on the chip prototype verification platform, the available debugging means are limited when problems occur during the verification process. It is usually to set the trigger signal, that is, add the signal list to be collected before compiling, and then set the trigger signal at runtime. When the trigger condition is met, the signal acquisition module can collect the signal of a period of time before and after the trigger condition and restore Create a waveform to analyze the problem with that waveform. However, in this method, the trigger signal needs to be set before compilation. Once there is an omission, it needs to be recompiled, which not only requires more time cost, but also needs to consider the platform resources, the number of collect...
