The Design And Test Of USB 3.0 Signal Integrity Simulation

In the 21st century, information systems development is very rapid, and thus the frequency and signal transmission rate clock is also put forward higher requirements. Resolution and storage performance is essential in today’s electronic product performance requirements. Meanwhile, with the continuous improvement of electronic products, consumer demand, and promote electronic products for each rate, and storage performance requirements. Broadband Internet connection is one of the major media, and the user is the realization of communication and interaction with a variety of media over the Internet. Transfer performance broadband transmission speeds largely determine the user’s satisfaction. Rapid transmission performance to achieve the user to quickly download, global media sharing. One of the products play an important role in providing a simple and convenient to the user’s connectivity is USB 3.0. USB3.0 with transmission speed, easy to use and fast, etc., to meet the latest requirements of the USB specification. To use a computer USB 3.0, and realized his basic functions, you need to realize is mounted to adapt some of the hardware in the computer, where the integrity of the design and test signals play in the research and development of USB 3.0 applications a particularly important role.This paper introduces the USB bus features, introduces the concept of information on USB3.0 and USB2.0 compared with analyzes of the architecture and features of USB3.0 data transfer, introduces the basic concepts of signal integrity analysis the definition of high-speed signal transmission line theory, impedance, differential line, reflections, crosstalk, jitter, etc., from the frequency domain analyzes S parameters, signal integrity analysis, simulation analysis in the time domain, the signal waveform analysis. USB3.0 simulation design were carried out based on the Intel Romley platform USB circuit design, laminated design, line width from the design, the impedance of the design, such as the design topology. Finally, a USB3.0 testing and analysis, and the test results are given USB3.0 signals.In this paper focused on the high-speed signal integrity, made a number of improvements and modifications such as design specifications, for the third generation serial hard drive interface (SATA3.0) also designed to promote and inspire their role.
