ChannelExpert – Channel Exploration

High speed serial channel design is becoming more and more challenging because of the ever increasing data rate. At multi-gigabit per second data rate, channel designers must characterize all the pieces in the signal path from transmit to receiver including connector, via, and trace, which are typically represented by either S-parameter blocks or RLGC transmission line (TML) model. Conventional SPICE-like circuit simulator has difficulty to efficiently handle the channel with mixed S-parameter and TML models, especially with large number of ports. ChannelExpert provides a fast and accurate way to address the signal integrity issue arising from the cascaded network of S-parameter blocks and TML models. Its frequency domain cascading technology and 2D RLCG full wave transmission line solver enable quick and accurate channel simulation. Its intuitive graphic interface lets you easily design, analyze and optimize your high speed serial links for compliance with design standards. Its quick channel build by table allows easy channel setup. Its parametric support enables the quick what-if analysis by sweeping the different S-parameter models for the channel element
