C**Functional Description ###func_descript###
This chapter describes the functional description and the design examples of the ALTUFM IP core. This
section also includes the ports descriptions of the ALTUFM IP core. You can use the ports to customize the
ALTUFM IP core according to your application.
Upgrading IP Cores
IP core variants generated with a previous version of the Quartus II software may require upgrading before
use in the current version of the Quartus II software. Click Project > Upgrade IP Components to identify
and upgrade IP core variants.
The Upgrade IP Components dialog box provides instructions when IP upgrade is required, optional, or
unsupported for specific IP cores in your design. You must upgrade IP cores that require it before you can
compile the IP variation in the current version of the Quartus II software. Many Altera IP cores support
automatic upgrade.
The upgrade process renames and preserves the existing variation file (
.v
, .
sv
, or
.vhd
) as
_
BAK.v
,
.sv
,
.vhd
in the project directory.

IP Core Status
You must upgrade the IP variation before compiling in the current version of
the Quartus II software.
Required Upgrade IP
Components
Upgrade is optional for this IP variation in the current version of the Quartus II
software. You can upgrade this IP variation to take advantage of the latest
development of this IP core. Alternatively you can retain previous IP core
characteristics by declining to upgrade.
Optional Upgrade IP
Components
Upgrade of the IP variation is not supported in the current version of the Quartus
II software due to IP core end of life or incompatibility with the current version
of the Quartus II software. You are prompted to replace the obsolete IP core with
a current equivalent IP core from the IP Catalog.
Upgrade Unsupported
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• Archive the Quartus II project containing outdated IP cores in the original version of the Quartus II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.
