Generating IBIS Files with Quartus II Software

Quartus^® II software includes a feature that automatically generates an IBIS file based on the design pin-out scheme. With this feature, Quartus II software selects the appropriate IBIS model for each pin in the design and creates a design-specific IBIS file.

Procedures

To generate an IBIS file for your Quartus II design project, follow these steps:

1. Under the Assignments menu, open the EDA Tool Settings dialog box (as shown below).
2. Under the EDA Tool Settings category, click Board-Level.
3. From the Board-level signal integrity analysis Format drop-down menu, select IBIS. Click OK.

4. To print the IBIS models with per pin RLC package information, select Print per pin RLC package model with mutual coupling. (1)
5. Compile your design.

After compilation, a design-specific IBIS file is generated with an .ibs extension in the <Quartus II project>/board/ibis directory.

Note:

1. The Quartus II software generated IBIS models with per pin RLC package model with mutual coupling information are supported in Quartus II software for new device IBIS models starting from Cyclone^® III and Stratix^® III device IBIS models.

For more information on generating IBIS files, refer to Quartus II Help.

Quartus II IBIS Models Support Matrix

Table 1 shows the revision of the IBIS file for each device family used in various Quartus II software versions at the time of release. Find the version of the IBIS file under [File Revision] keyword in the IBIS file (.ibs). The link to each device contains the IBIS models support files to Quartus II which may be newer than the latest Quartus II version has.

Note:
1. Beginning with Cyclone III and Stratix III devices, the zipped Quartus II files for new device IBIS models contain per pin RLC package models with mutual coupling information.

2. Beginning with Quartus II 9.0 and Stratix III devices, the IBIS model files supported in Quartus II are in xml format.

The Quartus II software will use the most current IBIS file available at the time of release. Since the IBIS models are asynchronously released and updated with Quartus II releases (either major releases or service pack releases), the IBIS files generated by the Quartus II software may not contain the most updated IBIS models. Check the IBIS Index page for the most updated IBIS files.

To generate an IBIS file using the most updated IBIS models in the Quartus II software, perform the following steps:

1. Download <device>_quartus.zip file in Table 1. The zip file contains the following files:
   
   
   1. <device>_ibis_properties.txt or <device>_ibis_properties.xml (2)
   2. <device>_ibis_models.txt or <device>_ibis_models.xml (2)
   3. <device>_package_rlc.txt or ><device>_package_rlc.xml (2)
   4. <device>_ibis_common.xml (2)
   5. <device>.pkg (1)
2. Unzip these files into your <Quartus II installation>/eda/ibis directory.
3. Right click and save the ibis_general.xml file to your <Quartus II installation>/eda/ibis directory.
4. The download files in Table 1 are only compatible with the latest Quartus II software.

Note:
1. This is only applicable to new device IBIS models starting from Cyclone III and Stratix III device IBIS models.

2. This is only applicable to device IBIS models starting from Stratix III device IBIS models.
