We present a statistical approach that improves the modeling of Intersymbol Interference for the design and validation of High-Speed Serial Links. The method combines the computational advantages of a statistical technique and the accuracy in modeling the realistic pulse shape of a Spice simulation. Results obtained with the proposed approach are compared with Spice simulations of a 2.5 Gb/s CMOS differential transmitter driving different types of channel. Good agreement with the reference Spice simulations is achieved with a drastic reduction of computation time.
