Signal integrity simulation design of image processor PCB combined with electromagnetic compatibility analyses based on Altium Designer 6

With the coming of the high-speed digital system age, signal integrity (SI) and electromagnetic compatibility (EMC) should not be ignored any more. In this paper, based on basic theories of SI and EMC, the high-speed digital design method for PCB using the SI simulation tool of Altium Designer 6 and EMC analyses is introduced, and the impedance control, power integrity (PI) design and SI (reflections and crosstalk) design of a piece of image processor PCB are demonstrated in detail. The simulation results show that the impedance control is perfect, reasonable termination can improve the waveforms and control the reflections and crosstalk.
