Backchannel Modeling and Simulation Using Recent Enhancements to the IBIS Standard

October 18, 2018 Cadence PCB Solutions

Recent enhancements to the upcoming IBIS standard now support backchannel training, enabling IBISAMI models to emulate this real-world SerDes behavior. AMI modelers now can incorporate backchannel algorithms into their IBIS-AMI models, automating the optimization of transmitter and receiver equalization settings in the same manner as their actual SerDes hardware devices. This saves system designers significant time by avoiding a multitude of computationally intensive sweeping to determine optimum equalization settings for their link, while at the same time yielding more realistic and higher quality results that are more consistent with the hardware they seek to model.
