Design and Simulate SerDes Systems

Design and simulate SerDes systems using the SerDes Designer app

High-speed electronic systems suffer from signal degradation caused by various impairments such as impedance mismatch, attenuation, and crosstalk. Using the equalization and gain modulation blocks in the SerDes Toolbox™, you can compensate for the distortions introduced by the lossy channels.

Starting with the SerDes Designer app, you can design the top-level SerDes systems and perform statistical analysis. Use the building blocks and system objects to design, configure, simulate and analyze the SerDes system including the transmitter and the receiver.
