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". The Clock Report is not displayed in the non timing-driven mode.
