The I/O Buffer Information Specification-Algorithmic Modeling Interface (IBIS-AMI) enables sharing of a model, which encompasses the complexity of the transmitter and receiver blocks. The IBIS-AMI model outputs an equalized waveform along with sampling information to the EDA tool. This paper gives an overview on sampling through the AMI_Init and AMI_GetWave flow part of the IBIS specification along with insight into reserved parameters usage. Results through seven EDA tools in modelling three different sampling mechanisms show the importance of sampling information when modelling through the IBIS specification. This is an attempt to make model developers and model users aware of the importance of sampling when running channel simulations.
