If you do not hold a multi-device license, then when applying optimization scenarios in a layout database, you can work with only one device at a time.
No Multi-chip License Held
Manipulate the components within the layout and perform unraveling on the selected device.
Once you are satisfied with the component orientation and the I/O assignments, apply the scenario. See "Creating and Applying a Layout Scenario" for more information.
The FPGA database will be updated with the new pin assignments. After the scenario is applied, the layout editor is returned to the “Initial Scenario”. The Initial Scenario does NOT reflect the changes on the previously selected device. All other scenarios are deleted.
Export symbols and schematics for the device by selecting Export > Schematic and Symbols, and forward annotate the changes to the PCB tool.
You can now import the PCB layout into the layout database in order to optimize another device with the results of the first device optimization.
Multi-chip License Held
Manipulate the components within the layout and perform unraveling. See "Unravel Nets" for more information. You can also use Unravel All FPGAs to unravel.
Once you are satisfied with the component orientation and the I/O assignments on the selected device(s), apply the scenario. See "Creating and Applying a Layout Scenario" for more information.
All FPGA databases are updated with the new pin assignments. After the scenario is applied, the layout editor is returned to the “Initial Scenario”. The Initial Scenario does NOT reflect the changes on the previously selected device. All other scenarios are deleted.
