• Package—Package models are required in all IBIS models. JNEye includes the IBIS package model in
the simulation by default. You can choose other package models by changing the Package selection to
Custom and specifying the external package model (Channel type Package) as a channel component.
• IBIS Files—Click the file open button next to the IBIS File text box to select an IBIS model file. JNEye
scans through the IBIS file and allocates all available transmitter components and models. If JNEye
encounters the following issues in opening or interpreting the IBIS-AMI model, a warning message is
displayed.
• No transmitter component or model can be located.
• The DLL for the computer platform cannot be located. The IBIS-AMI model is platform
dependent. For example, a 32-bit DLL is required to simulate in a 32-bit link simulator and a 64-bit
DLL is required to simulate in a 64-bit simulator. A 32-bit DLL cannot simulate in a 64-bit DLL
simulator.
• The DLL occupies too much memory and JNEye was not able to load it. However, JNEye might be
able to run the simulation with such a DLL because of memory allocation differences in the JNEye
GUI and the simulation engine.
• Component—Select an IBIS component from the IBIS model.
• IBIS tab—The IBIS tab shows the following configuration parameters:
• Model—Select a device model within a component of an IBIS model.
• Model Selector—Select a model from the model selector list.
• Corner—Select the corner type of a device model. The choices are Typ, Min, and Max.
• AMI File—Shows the AMI file specified in the IBIS model.
Note: JNEye currently only supports device models with AMI modeling components.
• DLL File—Shows the DLL file specified in the IBIS model.
• Use External Termination—A checked box indicates that an external termination is used in the
simulation. The external termination (single-ended) is specified in the text box on the right. The
default setting is not using external termination and the default external termination (if applicable)
is 50 ohms (single-ended).
• Use Rising/Falling Waveform—If rising/falling waveforms are available in the IBIS model, the
rising/falling waveforms are used to model the transmitter by default. If you turn off this option,
ramp data (in the IBIS model) is used in the simulation.
• Automatic Jitter/Noise Update—A checked box allows automatic jitter/noise updates from the
IBIS-AMI model (available for models which are compliant with IBIS-AMI 6.0 and later).
• Manual Jitter/Noise Update—When the Automatic Jitter/Noise Update option is disabled,
turning on this option allows you to manually update the jitter/noise figures from the IBIS-AMI
model (available for models which are compliant with IBIS-AMI 6.0 and later).
AMI tab
The AMI tab shows the following AMI configuration parameters.
