ChannelExpert – Channel Exploration


Overview

It is challenging for digital system designers to simulate high-speed SerDes channels. There are many different simulation scenarios to cover ranging from pre-layout/post-layout, frequency-domain/time-domain/statistical analysis, compliance check, to TX/RX optimization. ChannelExpert offers many built-in channel templates to support pre-layout exploration. Parametric S-parameters and transmission line models are supported for easy channel exploration. For the post-layout scenario, it can extract the desired channels with or without crosstalk from physical layout with transmission line and 3D via models automatically generated with built-in solvers. Its powerful multi-board channel extraction allows SI engineers to establish the board-to-board connection through pin mapping and automatically extract channels across different boards. IBIS-AMI with various equalization techniques is supported for channel simulation. Channel Operating Margin (COM) is incorporated in the tool to enable a quick check. Industry standards for Ethernet, computing, storage, etc. are also embedded to enable easy compliance checking.
