Paper Abstract

On account of high performance requirement of video processing systems and the shortcoming of conventional circuit design method, a design methodology based on the signal integrity (SI) theory for the high-speed video processing system with TI's digital signal processor TMS320DM642 was proposed. The PCB stack-up and construction of the system as well as transmission line characteristic impedance are set and calculated firstly with the impedance control tool Si8000 through this methodology. And then some crucial signals such as data lines of SDRAM are simulated and analyzed with the IBIS models so that reasonable layout and routing rules are established. Finally the system's highdensity PCB design is completed on Cadence SPB15.7 platform. The design result shows that this methodology can effectively restrain signal reflection, crosstalk, rail collapse noise and electromagnetic interference (EMI). Thus it significantly improves stability of the system and shortens development cycles.
