This design was based on the EDA technique. This paper introduce the development situation of EDA technology and programmable logic devices first; Then review with development process about the digital storage oscilloscope; Then describes the use of the advantages of FPGA design and development of language and VHDL ISE software of digital respectively characteristics, then the oscilloscope design each module are introduced; Finally is about EDA technology development trend, and complete frontier in the process of graduation design some comments. The difficulty of this paper with the logical design and controller EAB (embedded array blocks of data store FIFO implemented through the use of state machine design and realization of the control logic control through relevant ADC, the logic program design can see VHDL language has a lot of advantages and characteristics. As a kind of electronic measurement oscilloscope the most common instrument, it can be used to observe various waveform shape, and intuitively shows waveform and time relationship. The principle of digital storage oscilloscope is first by d/a transformation to measured analog signals into digital signals, then deposited in the storage and finally in shows, and through several/mode converter restore for analog signals, then displayed in the display.
