Fast Algorithm for Determining Eye-Diagram Characteristics of Lossy Transmission Lines

A novel algorithm for fast and accurately determining the height and width of eye diagrams at the receiving ends of transmission lines is proposed. While the two parameters concerned in the conductive and dielectric losses in response to the impulse stimulus are derived, the transfer function associated with the propagation coefficient to represent the signaling mechanism on the eye diagram can be developed. A systematic flow is implemented to acquire the predictable eye diagrams in a good agreement with the analysis results by the time-domain circuit simulator for varying designed geometries.
