Serdes designs can have mechanisms to adapt the TX based on RX information from a 'backchannel'. This means that during a simulation, the TX could be changing filter taps. Could the experts here give their opinion on how(/if) this could be modeled in AMI?

1-If the TX filter is implemented in the AMI_Init(), would this mean a re-start of the simulation on every change in TX filter? 2-If the TX filter is implemented in the AMI_GetWave(), how would this change in parameters be communicated to AMI_Getwave()? as it has no input parameter set. 3-Is there a defined way in which such(or any) RX information can be passed to the TX at run time(in an AMI environment)?

Thanks,
Akshaye
