Figure 2-43: Receiver IBIS-AMI Model Status Tab

Note: Consider the following for the IBIS-AMI receiver modeling support in JNEye:

• JNEye only supports the IBIS model with an AMI component. An IBIS model without an AMI

component will not be simulated.

• Rx_Receiver_Sensitivity is not supported in this JNEye release

• Receiver CDR is supported by the IBIS-AMI model itself

• JNEye supports IBIS-AMI receiver models with the on-die S-parameter model using the rxic

IBIS-AMI keyword. When JNEye detects the rxic keyword, the Channel Wizard helps you

determine the on-die S-parameter configuration.

Channel Setting

The channel connects the transmitter and the receiver. It contains transmission media such as PCB traces,

connectors, backplanes, cables, and device packages. A channel is a combination of numerous

components described by channel models. JNEye’s channel processing engine first interprets the channel

models and then cascades channels to construct one channel component for link simulations.
JNEye supports single-ended Touchstone S-parameter channel models. It can access and process n-port

S-parameters and extract transmission responses and crosstalk responses. After successfully extracting the

channel characteristics, it performs differential-pair channel cascading for subsequent link simulation.
Note: Make sure the single-ended Touchstone S-parameter is used in JNEye. Unexpected results will be

seen if you use a mixed-mode (or differential-mode) S-parameter in a simulation. If you receive a

mixed-mode S-parameter file, Altera recommends you convert it to single-ended format using

third-party tools. Consult your Altera supporting team if you have questions about this subject.

JNEye implements the Link Designer, which allows you to graphically construct the communication link.

In the following figure, the Channel List shows the channel construction example with one transmission

channel (such as a loss channel or a victim channel) and two crosstalk channels.
