No user timing constraints were detected or you have set the option to ignore timing constraints ("par -x"). Place and Route will run in "Performance Evaluation Mode" to automatically improve the performance of all internal clocks in this design. Because there are not defined timing requirements, a timing score will not be reported in the PAR report in this mode. The PAR timing summary will list the performance achieved for each clock. Note: For the fastest runtime, set the effort level to "std". For best performance, set the effort level to "high". N/A entries in the Constraints List may indicate that the constraint is not analyzed due to the following: No paths covered by this constraint; Other constraints intersect with this constraint; or This constraint was disabled by a Path Tracing Control. Please run the Timespec Interaction Report (TSI) via command line (trce tsi) or Timing Analyzer GUI.
