1.2.2. Initial Timing Constraint Guidelines

For best results, use realistic timing requirements for initial compilation. Applying more stringent timing requirements than the design requires can cause the Compiler to increase performance at the expense of resource usage, power utilization, or compilation time.

Specifying comprehensive timing requirement settings helps you to achieve the best results for the following reasons:

  • Comprehensive timing assignments enable the Compiler to work hardest to optimize the performance of the timing-critical parts of the design. This optimization can also save area or power utilization in non-critical parts of the design.
  • If enabled, the Intel® Quartus® Prime software can performs physical synthesis optimizations based on the comprehensive timing requirements.

Following compilation and timing analysis, the Compilation Report reports whether the design meets the timing requirements. You can then use the Intel® Quartus® Prime Timing Analyzer reporting commands to provide detailed information about all timing paths.
