4.1 Simulation Setup

Figure 4-1 is an example simulation setup. It consists of ideal Tx and Rx models, lossy channels, and the TDP1204 IBIS-AMI model.

The 12 Gbps source is an ideal Tx_Diff model available in ADS's Signal Integrity - Common Components palette. As the model is based on voltage sources, the series resistors are added to mimic the desired source output impedance and establish desired output amplitude.

The TDP1204 model consists of AMI IBIS-AMI model and RX_term and TX_term S-parameter models representing the device package and internal termination. The model parameter may be easily adjusted using the TDP1204 VAR EQN function.

An ideal Rx_Diff is also included. It is available in ADS's Signal Integrity - Common Components palette.
