Migrating IP Cores to a Different Device
IP migration allows you to target the latest device families with IP originally generated for a different device.
Some Altera IP cores require individual migration to upgrade. The Upgrade IP Components dialog box
prompts you to double-click IP cores that require individual migration.
1. To display IP cores requiring migration, click Project > Upgrade IP Components. The Description field
prompts you to double-click IP cores that require individual migration.
2. Double-click the IP core name, and then click OK after reading the information panel.
The parameter editor appears showing the original IP core parameters.
3. For the Currently selected device family, turn off Match project/default, and then select the new target
device family.
4. Click Finish, and then click Finish again to migrate the IP variation using best-effort mapping to new
parameters and settings. Click OK if you are prompted that the IP core is unsupported for the current
device. A new parameter editor opens displaying best-effort mapped parameters.
5. Click Generate HDL, and then confirm the Synthesis and Simulation file options. Verilog is the parameter
editor default HDL for synthesis files. If your original IP core was generated for VHDL, select VHDL to
retain the original output HDL format.
6. To regenerate the new IP variation for the new target device, click Generate. When generation is complete,
click Close.
7. Click Finish to complete migration of the IP core. Click OK if you are prompted to overwrite IP core
files. The Device Family column displays the migrated device support. The migration process replaces
<my_ip>
.qip
with the <my_ip>
.qsys
top-level IP file in your project.
If migration does not replace <my_ip>
.qip
with <my_ip>
.qsys
, click Project > Add/Remove Files
in Project to replace the file in your project.
Note:
8. Review the latest parameters in the parameter editor or generated HDL for correctness. IP migration
may change ports, parameters, or functionality of the IP core. During migration, the IP core's HDL
generates into a library that is different from the original output location of the IP core. Update any
assignments that reference outdated locations. If your upgraded IP core is represented by a symbol in a
supporting Block Design File schematic, replace the symbol with the newly generated <my_ip>
.bsf
after
migration.
The migration process may change the IP variation interface, parameters, and functionality. This
may require you to change your design or to re-parameterize your variant after the Upgrade IP
Note:
Components dialog box indicates that migration is complete. The Description field identifies IP
cores that require design or parameter changes.
