IBIS Models Support in Eldo
IBIS Algorithmic Model Interface (AMI)
row = row index , ranges from 0 to row_size−1
col = column index, ranges from 0 to aggressors
The first column of the impulse matrix is the impulse response for the primary channel. The
rest are the impulse responses from aggressor drivers to the victim receiver.

• row_size=value
The number of rows in impulse_matrix. It is a non-zero integer value. Default value is 1.
• aggressors=value
The number of aggressors in the impulse_matrix. It is a non-negative integer number.
Default value is 0. If both row_size and aggressors are provided their product should match
the number of values given in the impulse_matrix file.
• sample_interval=value
This is the sampling interval of the impulse_matrix and the input_waveform.
• bit_time=value
The bit time in the input_waveform.
• input_waveform="input_wave_file"
References a file that contains the test waveform. The waveform values are in Volts and are
uniformly spaced in time. The sample spacing is given by the parameter sample_interval.

Description
When instantiating an IBIS instance in the AMI mode, Eldo loads the AMI shared library, calls
the AMI API functions and passes to them the impulse matrix and the other required
