Package Models

The package models used in this kit are based on Xilinx S-parameter data. These models
provide typical case data and can be replaced by package models for specific packages and
applications.

Channel Models

This kit includes sample channel models for 22-inch, 36-inch, and 56-inch Xilinx and Tyco
backplane channels
from a single wrapper file. The Tyco channels have their own wrapper files. This allows the
channel model to be defined as a variable and selected via a drop-down menu in the
Solution Space portion of the Quantum Channel Designer GUI.
