1.4.3.3. Customizing Downloaded IBIS Models for Stratix® 10 Devices, Arria® 10 Devices, and Cyclone® 10 GX Devices

You can download the IBIS models for Stratix® 10 devices, Arria® 10 devices, and Cyclone® 10 GX devices from the Intel website. You can use these IBIS models directly to perform early simulations of the I/O buffers that you expect to use in your design as part of a pre-layout analysis.

These downloaded IBIS models have the RLC package values set to only one particular device in each device family. These generic models describe only a certain set of models listed for each device at: IBIS Models for Intel FPGA Devices.

To simulate your design with the most accurate model, you must customize the .ibs files to adjust the RLC values for accurate device package data. Customize the IBIS model file to match the values for your particular device package by performing the following steps:

  1. Download and expand the ZIP file (.zip) of the IBIS model for the device family you are using for your design. The .zip file contains the .ibs file along with an IBIS model user guide and a model data correlation report.
  2. Download the Package RLC Values spreadsheet for the same device family.
  3. Open the spreadsheet and locate the row that describes the device package used in your design.
  4. From the package’s I/O row, copy the minimum, maximum, and typical values of resistance, inductance, and capacitance for your device package.
  5. Open the .ibs file in a text editor and locate the [Package] section of the file.
  6. Overwrite the listed values copied with the values from the spreadsheet and save the file.
