Tiles
The FPGA is made up of a grid of tiles. Most tiles are for logic/routing and others are for functions like RAM, multipliers, or DSP. The following table shows the types of tiles by family and their use.
| Tile | Trion | Titanium | Topaz | Used for |
|---|---|---|---|---|

| RAM | |

| MULT | |

When you view your design's placement in the Floorplan Editor, you can click on a tile to view its type and other details. In the following figure, the selected blue tile is an EFT and is used for logic.
Tip: The Floorplan Editor provides a graphical way to find logic you want to
constrain.
Notice that some tiles in the floorplan have a number. This number indicates how many routing lines are used in that tile. A tile used for logic (blue) can also be used as routing (indicated by the number). Orange means a tile is only used as routing.
