Problems solved by technology

[0002] During the FPGA development process, users need to obtain one or more signal change information and the timing information of the change relationship between multiple signals; in the existing scheme, it is difficult to quantitatively record and feed back one or more signal change information, and it is difficult to observe multiple Signal timing relationship; in addition, in addition to the current real-time feedback signal, the user usually needs to review the previous signal of a specific period of time, but the existing scheme is also unable to achieve

Abstract

The invention discloses a waveform sampling debugging method for a remote experiment platform, which comprises the following steps that: after receiving a programming success signal returned by an FPGA, a back-end server establishes a start timestamp by taking the system time of the back-end server as a reference, samples the signal of the FPGA in real time, and feeds back signal data with the timestamp to a front-end server; and the front-end server receives the signal data with the timestamp, and draws an oscillogram of signal data change in a period of time by taking the timestamp as a horizontal axis in a table drawing mode. According to the method, the operations of reading data and recording data in an experiment are simplified, so that a user can visually know the output of the FPGA, and the user can find problems and debug codes more quickly.

Description

technical field [0001] The invention relates to the technical field of computer network communication, in particular to a waveform sampling and debugging method for a remote experiment platform. Background technique [0002] During the FPGA development process, users need to obtain one or more signal change information and the timing information of the change relationship between multiple signals; in the existing scheme, it is difficult to quantitatively record and feed back one or more signal change information, and it is difficult to observe multiple Signal timing relationship; in addition, in addition to the current real-time feedback signal, the user usually needs to review the previous signal of a specific period of time, but the existing scheme is also unable to achieve. Contents of the invention [0003] The purpose of the present invention is to provide a waveform sampling and debugging method for a remote experiment platform, which can allow users to intuitively u...
