【Abstract】 Considering Signal Integrity(SI) and taking effective measures are inevitable problems in the field of high speed PCB design.The development period can be shortened and the cost can be reduced based on the high speed PCB design flow of signal integrity analysis.On the basis of it,a high speed data collection and transmission system was designed.The simulation illustrates signal integrity of the circuits is improved.The test about performance of the data collection system shows the dynamic effective bits of AD can reach 10 bits.It is shown that the simulation based on SI is not only feasible but also essential in high speed circuit design.更多还原
