Vivado reports SLR utilization by default. When you use the
-slr option, the report displays only the SLR-related utilization
data. The SLR utilization section includes four tables:
- SLR Connectivity
- SLR Connectivity Matrix
- SLR CLB Logic and Dedicated Block Utilization
- SLR IO Utilization
For UltraScale families, the SLR connectivity table shows the number of SLR crossing registers used for both TX and RX directions on each SLR side. For other device families, the table shows only the number of crossings used, because those devices do not include dedicated crossing registers.
