3.4.1. Ignored Timing Constraints

The Intel® Quartus® Prime software ignores illegal, obsolete, and conflicting constraints.

You can view a list of ignored constraints in the Timing Analyzer GUI by clicking Reports > Report Ignored Constraints or by typing the following command to generate a list of ignored timing constraints:

report_sdc -ignored -panel_name "Ignored Constraints"

Analyze any constraints that the Intel® Quartus® Prime software ignores. If necessary, correct the constraints and recompile your design before proceeding with design optimization.

You can view a list of ignored assignment in the Ignored Assignment Report generated by the Fitter.
