NOTES:
|
| 52 |
|
|
|
| 53 |
|
|
Related logic is defined as being logic that shares connectivity - e.g. two
|
| 54 |
|
|
LUTs are "related" if they share common inputs. When assembling slices,
|
| 55 |
|
|
Map gives priority to combine logic that is related. Doing so results in
|
| 56 |
|
|
the best timing performance.
|
| 57 |
|
|
|
| 58 |
|
|
Unrelated logic shares no connectivity. Map will only begin packing
|
| 59 |
|
|
unrelated logic into a slice once 99% of the slices are occupied through
|
| 60 |
|
|
related logic packing.
|
| 61 |
|
|
|
| 62 |
|
|
Note that once logic distribution reaches the 99% level through related
|
| 63 |
|
|
logic packing, this does not mean the device is completely utilized.
|
| 64 |
|
|
Unrelated logic packing will then begin, continuing until all usable LUTs
|
| 65 |
|
|
and FFs are occupied. Depending on your timing budget, increased levels of
|
| 66 |
|
|
unrelated logic packing may adversely affect the overall timing performance
|
| 67 |
|
|
of your design.
