Serial Link Design Concepts
Using the Serial Link Designer app, you can analyze serial link projects for pre-layout and post-layout simulations. The app uses an iterative and sequential process to find an optimal solution based on the design requirements. You can organize the data using transfer nets.
The app allows you to design, simulate, and test AMI models with PAMn signaling. You can also enable different clock modes. For faster processing, the app allows you to run simulations in parallel if you have license to Parallel Computing Toolbox™.

Channel Operating Margin (COM) for Serial Link
Use channel operating margin (COM) within a Serial Link Designer project that has an interface that operates at 100 GT/s per Lane with NRZ modulation. COM is a figure of merit for a passive channel that gives you insight on the quality of the channel design. To calculate COM, use the ratio of signal amplitude factors to noise amplitude factors. Several factors such as channel bit rate, insertion loss, return loss, cross-coupling, transmitter and receiver equalization, and IC package models are applied to determine COM. COM is a valuable part of channel design methodology in general and is required for compliance in some applications such as IEEE 802.3 and OIF CEI standards. For more information on how to calculate and set up COM and how to interpret COM results, see Channel Operating Margin (COM).
