Document Table of Contents Characterization Data Access

You can retrieve the receiver jitter values from the built-in device characterization database. Intel® Advanced Link Analyzer supports Arria® 10 GX/SX/GT, Stratix® V GT, Stratix® V GX and Arria® V GZ characterization database access upon request. For devices supported by IBIS-AMI Wrapper Technology, jitter/noise models are provided by the IBIS-AMI models, and the wrapper determines the correct jitter/noise values associated with the link settings. If you need this capability, contact My Intel support.

Use the following guidelines for characterization data access:

  • When Stratix® V GX, Stratix® V GT, Arria® V GZ or Arria® 10 GX/SX/GT is selected, the Characterization Data Access button appears and you can include the receiver jitter parameters in the simulation.
  • Characterization Data Access covers PVT variations. You can select the appropriate process, voltage, and temperature conditions that best match the desired operation conditions.
  • After clicking Characterization Data Access, Intel® Advanced Link Analyzer is configured to use the characterization data by:
    • Setting Jitter/Noise Component Mode for characterization data entries
    • Turning on the Jitter/Noise Data Lock
    • Importing device characterization data based on the jitter unit selection
      • RJ—Unit selection can be UI (RMS) or ps (RMS)
      • Other Jitter—Unit selection can be UI (pk-pk), UI (pk), ps (pk-pk), or ps (pk)

The Intel® Advanced Link Analyzer simulation engine uses this characterization data from the database.

  • Stratix® 10 receiver's jitter and noise values are sourced from the IBIS-AMI models or from user inputs per the IBIS-AMI model's documents.
  • The characterization data is displayed in the text box for reference purposes. The Intel® Advanced Link Analyzer simulation engine uses proprietary algorithms to accurately model the jitter and noise in the simulations.
  • You can unlock the jitter and noise contents by turning off the Jitter/Noise Data Lock. However, the jitter and noise models and values can be different from those when the Jitter/Noise Data Lock is turned on.
  • Characterization Data Access is supported when the data rate is in the following range:
    • Stratix® V GX: 5 Gbps to 14.1 Gbps
    • Stratix® V GT: 19.6 Gbps to 28.1 Gbps
    • Arria® V GZ: 5 Gbps to 14.1 Gbps
    • Arria® 10 GX/SX: 3 Gbps to 17.4 Gbps
    • Arria® 10 GT: 3 Gbps to maximum data rate specified in the data sheet
    When the data rate is out of the specified range, Intel® Advanced Link Analyzer displays a warning message, and no jitter data is retrieved. If you change the data rate, you must retrieve the new jitter data by clicking Characterization Data Access.
  • After changing the link and device configurations, such as data rate, bandwidth, and PVT condition, you must update the jitter value by clicking Characterization Data Access.
  • When the Jitter/Noise Data Lock is turned on, Intel® Advanced Link Analyzer examines whether the jitter data matches the simulation configuration during the following conditions:
    • Start simulation
    • Save link configuration
    • In batch simulation mode, jitter data is retrieved and calculated based on the link configuration

    When the link configuration exceeds the supporting range of Characterization Data Access, a warning message (conditions 1 and 2) is shown and jitter is reset (all conditions).
