IBIS Models for Intel® Devices

The input/output buffer information specification (IBIS) is a device-modeling standard that was developed in 1993 by a consortium of companies from within the electronic design industry. IBIS allows the development of device models that preserve the proprietary nature of integrated circuit device designs, while at the same time providing information-rich models for signal integrity and electromagnetic compatibility (EMC) analysis.

IBIS models for Intel^® devices support a wide variety of I/O features and cover minimum, typical, and maximum process, voltage, and temperature conditions. Information contained within the IBIS files is for modeling purposes only and is not guaranteed.

Read the instructions on how to use IBIS models in your simulations, or learn more on generating IBIS files with Intel^® Quartus^® Prime software.

Table 1 explains the IBIS File Revision Numbering Convention used in new device IBIS models starting from Cyclone^® III and Stratix^® III device IBIS models.

Notes:

1. Files in this column show the supported IBIS models. Updates to this column will not be reflected on the date listed in the 'Last IBIS Model Update' column. An tag indicates the most recently updated file.
2. Files in this column show the resistance, inductance, and capacitance values for different packages. Updates to this column will not be reflected on the date listed in the 'Last IBIS Model Update' column. An tag indicates the most recently updated file.
3. These 3 columns are inter-related. In each row, the 'IBIS Model Revision' column shows the IBIS model version contained in the zip file of the 'IBIS Model' column, while the 'Last IBIS Model Update' column corresponds to the date the zip file was uploaded.
