Working with Projects and Implementations Chapter 4. Tasks
Saving Implementations
To save the state of the database (options, netlist, constraints, placement, and routing data) for an
implementation in a project in the workspace:
1. Activate an implementation in the Projects View.
2. Run the flow (at least through Run Prepare)
3. Optionally edit placement or routing information
4. Click on the Save Implementation toolbar button ( ) in the Projects view.
5. In the Save Implementation dialog, type in the file path to the Acxdb Archive File to save the
implementation’s data to and click Finish.
After clicking Finish, the state of the database (options, netlist, constraints, placement, and routing data) for
the implementation will be stored in the Acxdb Archive file, which can be restored again later.

Legacy Support for Acx Files
As of ACE 3.0, Place and Route data is no longer saved and restored using .acx files (by default) as in
previous releases. Loading and saving place and route data is now done using the new save/restore
implementation functionality using Acxdb Archive Files.
Support for the old .acx files has been removed from the ACE GUI, but can still be accessed via the
TCL command interface. If you would like save place and route data to an Acx file, you can use the
save place and route command.
Restoring Implementations
To restore the state of the database (options, netlist, constraints, placement, and routing data) for an
implementation in a project in the workspace:
1. Activate an implementation in the Projects View.
2. Click on the Restore Implementation toolbar button ( ) in the Projects view.
3. In the Restore Implementation dialog, type in the file path to the Acxdb Archive File to restore the
implementation’s data from and click Finish.
After clicking Finish, the state of the database (options, netlist, constraints, placement, and routing data) for
the implementation will be restored from the Acxdb Archive file.
Note: the Run Prepare, Run Place, and Run Route flow steps automatically save checkpoint Acxdb files (by
default) that may be restored later.
Legacy Support for Acx Files
As of ACE 3.0, Place and Route data is no longer saved and restored using .acx files (by default) as in
previous releases. Loading and saving place and route data is now done using the new save/restore
implementation functionality using Acxdb Archive Files.
Support for the old .acx files has been removed from the ACE GUI, but can still be accessed via the
TCL command interface. If you would like load place and route data from an Acx file, you can use the
load place and route command.
Recommendation: After restoring an implementation from a legacy .acx file, save the implementation to an
Acxdb Archive File to migrate to the new save/restore process.
