The layout database is an I/O optimization environment that allows you to optimize the I/O assignments based on a component orientation. Data is imported into the layout database from the schematic and the PCB layout tool or simply created from a netlist and PADS I/O Designer components. The editor within the database allows devices to be moved and new solution scenarios to be created. The best results can then be selected and propagated to the FPGA database.
| Note | |
|
For each board in the database, there can be only one Layout database. |

In order to work with a layout, add a layout database to a board within the project by selecting File > Add to Board > New Layout. You can only have one layout database per design.
When working within a layout database, the Layout Window, Pins List, Connectivity List Window and Layout Scenarios Window are used to optimize I/O assignments between components.
