development of this IP core. Alternatively you can retain previous IP core
characteristics by declining to upgrade.
Optional Upgrade IP

Upgrade of the IP variation is not supported in the current version of the Quartus

of the Quartus II software. You are prompted to replace the obsolete IP core with
a current equivalent IP core from the IP Catalog.

Before you begin
• Archive the Quartus II project containing outdated IP cores in the original version of the Quartus II
software: Click Project > Archive Project to save the project in your previous version of the Quartus II
software. This archive preserves your original design source and project files.
• Restore the archived project in the latest version of the Quartus II software: Click Project > Restore
Archived Project. Click OK if prompted to change to a supported device or overwrite the project database.
File paths in the archive must be relative to the project directory. File paths in the archive must reference
the IP variation
.v
or
.vhd
file or
.qsys
file (not the
.qip
file).
1. In the latest version of the Quartus II software, open the Quartus II project containing an outdated IP
core variation. The Upgrade IP Components dialog automatically displays the status of IP cores in your
project, along with instructions for upgrading each core. Click Project > Upgrade IP Components to
access this dialog box manually.
2. To simultaneously upgrade all IP cores that support automatic upgrade, click Perform Automatic
Upgrade. The Status and Version columns update when upgrade is complete. Example designs provided
with any Altera IP core regenerate automatically whenever you upgrade the IP core.
