|---|---|---|
1  | 
      Turn on Optimize multi-corner timing on the Fitter Settings page in the Settings dialog box.  | 
     |
2  | 
      Use create_clock and create_generated_clock to specify the frequencies and relationships for all clocks in your design.  | 
     |
3  | 
      Use set_input_delay and set_output_delay to specify the external device or board timing parameters.  | 
     |
4  | 
      Use check_timing to generate a report on any problem with the design or applied constraints, including missing constraints.  | 
     |
5  | 
      Use set_false_path or set_clock_groups for asynchronous paths.  | 
     
These assignments and settings are important for large designs such as those in Agilex™ 5 devices.
When you turn on the Optimize multi-corner timing option, the design is optimized to meet its timing requirements at all timing process corners and operating conditions. Therefore, turning on this option helps create a design implementation that is more robust across PVT variations.
In your Timing Analyzer .sdc constraints file, apply the recommended constraints to your design.
