IBIS Files: Click the file open button
(see Repeater/Retimer TX IBIS-AMI Configuration) next
to the IBIS File text box to select an IBIS model file.
Intel® Advanced Link Analyzer scans through the IBIS file
and allocates all available transmitter components and models. If
Intel® Advanced Link Analyzer 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 Intel® Advanced Link Analyzer was not able to load it. However, Intel® Advanced Link Analyzer might be able to run the simulation with such a DLL because of memory allocation differences in the Intel® Advanced Link Analyzer GUI and the simulation engine.
- Component: Select an IBIS component from the IBIS model
-
IBIS tab
- 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: Intel® Advanced Link Analyzer currently only supports device models with AMI modeling components.
- DLL File: Shows the DLL file specified in the IBIS model.
- Use External Termination: 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:
Allows automatic jitter/noise updates from the IBIS-AMI model
(available for models which are compliant with IBIS-AMI 6.0 and
later).Note: If you noticed very slow GUI response with certain IBIS-AMI models, turn off Automatic Jitter/Noise Update to see if the condition improves. You can import jitter/noise number using Manual Jitter/Noise Update.
- 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).
- DLL_Path: Specify a folder or path name where the supporting files of an IBIS-AMI model are stored. Refer to the IBIS standards for details.
- Model Option: Choose Default.
- Ideal Front-end Limiting Amplifier: If on, Intel® Advanced Link Analyzer inserts an ideal limiting amplifier before the repeater/retimer driver stage with a waveform differential amplitude of 1 V.
- AMI tab: Refer to IBIS-AMI Transmitter in the Characterization Data Access section for details.
- Jitter/Noise: Refer to IBIS-AMI Transmitter in the Characterization Data Access section for details.
- Status tab: Refer to IBIS-AMI Transmitter in the Characterization Data Access section for details.
- Jitter/Noise Options: Internal use only. Do not use and let it remain in its default state.
