Abstract
In this paper, a fast signal integrity methodology using pseudo eye is introduced to characterize printed circuit board (PCB) channels. The pseudo eye and pseudo ratio are proposed as performance indicators of the channel. This methodology can be applied to not only the solution space check during the pre-layout design phase but also layout quality check before PCB manufacture. For pre-layout analysis, the fast methodology can significantly reduce the required simulation resource and remove the complexity of chip behaviors with the equalization (EQ) function. Moreover, the PCB layout can be very efficiently checked and the potential routing issues can be quickly identified.
