Generating IBIS Files With Quartus II Software
The Quartus® II software includes a feature that automatically generates an IBIS file based on the design pin-out scheme. With this feature, the 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:
- Open the EDA Tool Settings dialog box under the Assignments menu (as shown below).
- Click on Board-Level under the EDA Tool Settings category.
- Select Signal Integrity (IBIS) from the Tool name drop-down menu. Click OK.
View full image in new window
- Compile your design.
- After compilation, a design-specific IBIS file will be generated with an .ibs extension in the <Quartus II project>/board/ibis directory.
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.
Notes to Table 1:
- Quartus II software version 5.0 and earlier.
- IBIS support for these device families are not available in this Quartus II software version.
- These devices are supported in the Quartus II software version 3.0 and later.
- These devices are supported in the Quartus II software version 3.0 service pack 1 and later.
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:
- Download <device>_quartus.zip file in Table 1. The zip file contains the following three text files:
- <device>_ibis_properties.txt
- <device>_ibis_models.txt
- <device>_package_rlc.txt
- Unzip these files into your <Quartus II installation>/eda/ibis directory.
- The download files in Table 1 are only compatible with the latest Quartus II software.
