| -Family     | The device family                                             |
+-------------+---------------------------------------------------------------+
| -Device     | The device number                                             |
+-------------+---------------------------------------------------------------+
| -MaxALMs    | The total number of ALMs in the device                        |
+-------------+---------------------------------------------------------------+
| -MaxM4Ks    | The total number of M4K memory blocks in the device           |
+-------------+---------------------------------------------------------------+
| -MaxRAMBits | The total number of RAM bits that can be stored in the device |
+-------------+---------------------------------------------------------------+
| -MaxDSPs    | The total number of DSP blocks in the device                  |
