4.4.3. Fmax Target Measuring Methodology

The specified Fmax target is measured using the following conditions:

  • IP is compiled as a stand-alone component, and is wrapped inside a wrapper.
  • The wrapper has 1 non-resettable flop layer to register all wrapper input and output ports except for clocks.
  • The wrapper flop layer must be preserved through synthesis attributes:
    (* altera_attribute = {"-name DONT_MERGE_REGISTER ON; -name PRESERVE_REGISTER ON; -name ADV_NETLIST_OPT_ALLOWED NEVER_ALLOW"} *)
  • All wrapper ports except for clocks are set as virtual pins.
Note: This measurement is not intended to validate actual IP performance when integrated into a real system.
