[Abstract]:With the development of acquisition and storage technology, the comprehensive performance of oscilloscope is more and more strong, and the function of oscilloscope is becoming more and more demanding, so the digital oscilloscope with various data processing functions comes into being. In the face of the massive data collected, how to analyze and process the oscilloscope quickly and effectively through the function module of oscilloscope becomes particularly important. Based on the research and development of the teaching and research team, this paper focuses on the theme of "hardware waveform analysis and waveform feature searching function module design". Three waveform analysis functions and seven basic waveform features search functions and nine bus protocol search functions are realized by FPGA and basic hardware circuit cooperative processing. The main contents of this paper are as follows: 1. Research on the whole structure of hardware waveform analysis and waveform feature search function. It mainly includes the principle of hardware waveform analysis and waveform feature search, the localization and synchronization of search results, and the interaction with other modules. From the whole hardware system of the digital fluorescence oscilloscope, the two functional modules studied in this paper are designed. 2. 2. The realization of waveform feature search function. In FPGA, edge, pulse width / burr, underamplitude, rise / drop time, build / hold time, The basic waveform feature search function of 7 types of sequence and timeout, and 9 kinds of bus protocol search function. 3. The realization of waveform analysis function. The waveform analysis function includes three basic waveform analysis functions: pass / failure analysis, template analysis and trajectory analysis. Hardware waveform analysis and waveform feature search function test and analysis. Including test platform and equipment, test process, test results and analysis. In this design, FPGA and hardware circuit are used to realize waveform analysis and waveform feature search, which overcomes the shortcoming of slow speed when analyzing and searching massive waveforms by software. The dead time of digital oscilloscope is shortened. At the same time, the bus search function is added to the search module, which enriches the searchable signal types of the digital oscilloscope.
