The Vivado implementation log includes:
- Information about the location, netlist, and constraints used.
- Logic optimization task. The tool runs logic optimizations by default to reduce utilization and improve design performance.
- The placement phases, plus a post-placement timing estimate (WNS and TNS only).
- The router phases, plus several timing estimates and an estimated post-routing timing summary (WNS, TNS, WHS, and THS only).
- Elapsed time and memory for each implementation command and phases.
Review this report or the proper section of the messages tab for errors, critical warnings, and warnings. The placer generates warnings that can be elevated to errors later in the flow. If using stepwise runs, the log contains only the results for the last step.
Important: Review this log
or the messages tab for errors, critical warnings, and warnings. The
synthesis tool can issue messages that cause serious issues later in the
design flow. Address them early to avoid downstream problems.
