2.1.3.3. Characterization Data Access
Characterization Data Access—Transmitter jitter values can be retrieved from the built-in device characterization database.
Note: Intel® Advanced Link Analyzer supports Arria® 10 GX/SX/GT, Stratix® V GT, Stratix® V GX, and Arria® V GZ, and Stratix® 10 L-tile/H-tile/E-tile 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, Arria® 10 GX/SX/GT, Stratix® 10 L-Tile/H-Tile/E-Tile/P-Tile, or Agilex™ 7 E-Tile/P-Tile is selected, the Characterization Data Access button appears, and you can include the transmitter jitter parameters in the simulation.
- Characterization Data Access covers PVT variations. You can select appropriate process, voltage, and temperature conditions that best match the desired operating conditions.
- After clicking the button, Characterization Data Access configures Intel® Advanced Link Analyzer to use the characterization data by:
- Selecting Jitter/Noise Component Mode for characterization data entries
- Turning on 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)
These actions inform the Intel® Advanced Link Analyzer simulation engine to use the characterization data from the database.
Note:
- 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 Jitter/Noise Data Lock. However, the jitter and noise models and values can differ from those when 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
- Stratix® 10 L-tile: 3 Gbps to maximum data rate specified in the data sheet (Typical PVT only)
- 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
- Stratix® 10 L-tile: As per Stratix® 10 L-tile specifications
- Stratix® 10 H-tile: As per Stratix® 10 H-tile specifications
- Stratix® 10 E-tile: As per Stratix® 10 E-tile specifications
- Stratix® 10 P-tile: As per Stratix® 10 P-tile specifications
- Agilex™ 7 E-tile: As per Agilex™ 7 E-tile specifications
- Agilex™ 7 P-tile: As per Agilex™ 7 P-tile specifications
- Agilex™ 7 R-tile: As per Agilex™ 7 R-tile specifications
- Agilex™ 7 F-tile: As per Agilex™ 7 F-tile specifications
- Agilex™ 5: As per Agilex™ 5 specifications
- After changing the link and device configurations, such as data rate, VOD, PLL type and bandwidth, and PVT condition, you must update the jitter value by clicking Characterization Data Access.
- When 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).
