The current Quartus® Prime Pro Edition software installation includes the Intel FPGA IBIS models and IBIS writer script for Agilex™ FPGA portfolio devices in /quartus/common/misc/ibis_writer/. In addition, you can download the latest models (without the script) from: IBIS Models for Intel FPGA Devices.

The downloaded or installed IBIS models have the RLC package values set to only one particular device in each device family. These generic models describe the full set of models listed for and supported by each device family at: IBIS Models for Intel FPGA Devices.

Alternatively, you can generate custom IBIS models for Agilex™ FPGA portfolio devices by using the Quartus® Prime EDA Netlist Writer GUI, as Generate Custom IBIS Models with the EDA Netlist Writer GUI describes.

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 using the IBIS Writer script. Use the script to customize the IBIS model file to match the values for your particular device package.

To use the IBIS Writer script, refer to the step by step instructions in the /quartus/common/misc/ibis_writer/README.txt file.
