Summary • No change to Tx Init • Augment Rx Init impulse matrix by two columns for total impulse and Rx DFE Rx Init Input Impulse Symbol Definition Impulse from upstream Tx input or output, depending on whether Tx has Get. Wave and whether simulation is in time domain or statistical, to Rx input Rx Init Output Impulse Symbol Definition Impulse of Rx’s non-DFE portion (including gain and linear EQ) Impulse from terminal Tx input to Rx input. Rx Init performs optimization based on this impulse Empty place holder for Rx Init to return DFE impulse Impulses from aggressors to Rx input 3/11/2021 Page 3

New Reserved Parameters New_Flow_Flag - Boolean, In, Optional, Default=False, Format=List{False, True} - Its presence

New Reserved Parameters New_Flow_Flag - Boolean, In, Optional, Default=False, Format=List{False, True} - Its presence in the. ami file indicates that the model support BOTH proposed and 6. 1 flow - A model that supports the proposed flow must also support the 6. 1 flow - If it’s not specified in the. ami file, the EDA tool executes the 6. 1 flow without setting its value in the AMI_parameters_in string when calling AMI_Init - If it’s specified and if the EDA tool execute the proposed flow, the tool sets its value to True in the AMI_parameters_in string when calling AMI_Init, and the model functions according to the proposed flow - If it’s specified and if the EDA tool execute the 6. 1 flow, the tool doesn’t set its value in the AMI_parameters_in string when calling AMI_Init 3/11/2021 Page 12
