The Signal Integrity of the High-Speed IC Design

With the continuous improvement of the Embedded Microprocessor´s main frequency, the signal transmission and processing becoming faster and faster, the traditional method of circuit design and software will not be able to meet the requirements of high-speed circuit design. However, an increasing number of VLSI chips´ work frequency has reached above 100MHZ, the CPU with 450MHz will also be widely used. The edge of the signal is becoming steeper and steeper (has reached ps), which makes high-speed system design must face a variety of signal integrity issues. This paper presents a number of common signal integrity issues, and the corresponding improvement of the program. In addition, in the premise of that consider signal integrity in the process of high-speed circuit design, given the specific design, given out the solution for important issues of signal integrity that must to consider during the whole process from the schematic diagram design to PCB placement and routing.
