Hi, Greg; In statistical simulation, adaptation is modeled by AMI_Init, which adjusts equalizer according to the channel characteristics and modifies the impulse response. It's similar to what you did with transient, except that in tan the EQ is adjusted based on the input signal waveform, but in AMI_Init EQ is adjusted based the input impulse.

To model adaptive equalization, I need to first run a short transient simulation, load the RX tap settings from that simulation into the model-specific parameters, and then run a statistical simulation. Question: what is it about modifying the impulse response that prevents RX adaptive equalization in statistical simulations? Thanks in advance for your time.
