ID:336004 The Timing Analyzer will use the Classic Timing Analyzer's FMAX_REQUIREMENT assignment (or --fmax command-line argument) as default timing requirement. Any other Classic Timing Analyzer assignment will be ignored.

CAUSE: The Timing Analyzer found no SDC file which means the design is not properly timing constrained and cannot be properly optimized. However, the Timing Analyzer is using the Classic Timing Analyzer Global Fmax requirement assignment or the --fmax command-line argument as the default timing requirement. The Timing Analyzer will automatically execute a 'derive_clocks -period' command with this global requirement. Note that no other Classic Timing Analyzer timing requirement will be honored.

ACTION: Intel strongly recommends that an SDC file is used to properly constrain the design. It is considered best practices to explicitly constrain each clock independently (and not use the derive_clocks command).
