The Vivado tools log file reports incremental placement and routing summary results from Incremental Compile.
Incremental Placement Summary
The following example of the Incremental Placement Summary includes a final assessment of cell placement reuse and run time statistics.
+-------------------------------------------------------------------------------+
|Incremental Placement Summary |
+-------------------------------------------------------------------------------+
| Type | Count | Percentage |
+-------------------------------------------------------------------------------+
| Total instances | 33406 | 100.00 |
| Reused instances | 32390 | 96.96 |
| Non-reused instances | 1016 | 3.04 |
| New | 937 | 2.80 |
| Discarded illegal placement due to netlist changes | 16 | 0.05 |
| Discarded to improve timing | 63 | 0.19 |
+-------------------------------------------------------------------------------+
|Incremental Placement Runtime Summary |
+-------------------------------------------------------------------------------+
| Initialization time(elapsed secs) | 79.99 |
| Incremental Placer time(elapsed secs) | 31.19 |
+-------------------------------------------------------------------------------+Incremental Routing Summary
The Incremental Routing Summary displays reuse statistics for all nets in the design. The categories reported include:
- Fully Reused
- The entire routing for a net is reused from the reference design.
- Partially Reused
- Some of the routing for a net from the reference design is reused. Some segments are re-routed due to changed cells, changed cell placements, or both.
- New/Unmatched
- The net in the current design was not matched in the reference
design.
