IBIS Models Support in Eldo<br />

IBIS Algorithmic Model Interface (AMI)<br />

parameters. According to the values of the AMI reserved parameters Use_Init_Output and<br />

GetWave_Exists, Eldo convolves the input waveform with the channel impulse matrix and<br />

passes the output to the AMI_GetWave API function.<br />

Eldo adds a .TRAN command and plots the final output waveform. The output waveform is<br />

provided in both differential and single-ended form. The name of the differential wave is<br />

_ami_out. The single ended wave names are _ami_out_diff<br />

and _ami_out_inv.<br />

The IBIS receiver buffer may be added to obtain the output after the digital level.<br />

For more details about the AMI API functions and the reserved parameters, please refer to the<br />

IBIS v5.0 specification document.<br />
