Tiles
|
|
^^^^^
|
|
|
|
The FPGA architecture follows a tile-based organization, to exploit the fine-grainularity in physical design, where three types of tiles are built:

|
| Type | Capacity | Description |
|
|
+======+==========+==============================================+
|
|
| CLB | 144 || Each CLB tile consists of |
|
|
| | || - a Configurable Logic Block (CLB) |
|
|
| | || - a X-direction Connection Block (CBx) |
|
|
| | || - a Y-direction Connection Block (CBy) |
|
|
| | || - a Switch Block (SB). |
|
|
| | | |
|
|
| | || This is the majority tile across the fabric |
|
|
| | | to implement logics and registers. |
|
|
+------+----------+----------------------------------------------+
|
|
| IO-A | 36 || The type-A I/O is a low-density I/O tile |
|
|
| | | which is designed to mainly interface |
|
|
| | || the GPIOs of the SoC. |
|
|
| | | |
|
|
| | || Each I/O-A tile consists of 1 digitial I/O |
|
|
| | | cell. |
|
|
+------+----------+----------------------------------------------+
|
|
| IO-B | 12 || The type-B I/O is a high-density I/O tile |
|
|
| | | which is designed to mainly interface |
|
|
| | || the wishbone interface and logic analyzer |
|
|
| | | of the SoC. |
|
|
| | | |
|
|
| | || Each I/O-B tile consists of 9 digitial I/O |
|
|
| | | cells. |
