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 available in each device's IBIS user guide on how to use IBIS models in your simulations. IBIS Models for Matured Intel Devices are no longer recommended as design-in products, the Mature Device Families are listed on Intel® FPGA Device Support Resources. For a comprehensive list of design-in products, see the Intel FPGA Product Catalog or contact your local sales office.
