TmlExpert – Fast and Accurate TML Modeling and Simulation


TmlExpert is a fast and accurate Tml modeling and simulation tool.
Transmission lines are key building components which plays an important role in signal integrity. As data rate increases to high Gbps speed, accurate modeling of transmission lines including wideband dielectric model, conductor surface roughness, and solder mask layer is becoming necessity. Calculating impedance with 2D RLGC solver is commonly used for impedance control purpose. Given the length of the transmission line, the S-parameter, TDR, delay, and resultant eye-diagram with bit stream input are often needed. In high speed PCB layout, serpentine traces are often used to meet timing specification. Tabbed routing is newly proposed to improve the route channel utilization. However, the signal integrity impact is required to be evaluated.
