(# WARNING[1]: <file name>(): No default binding for component: "scfifo". (Generic "maximize_speed" is not on the entity) - (# WARNING[1]: <file name>(): No default binding for component: "scfifo". (Generic "maximize_speed" is not on the entity) Description This warning message may occur when a MegaWizard ® -generated DCFIFO design from the Quartus ® II software version 4.0 is compiled in the Modelsim ® simulator. If you choose Yes (Best speed) under Output register option for devices with fully synchronous RAM on page 7 of the MegaWizard when generating the FIFO, the ModelSim software issues the compilation warning. To avoid this warning message with the Quartus II software version 4.0, comment out the maximize_speed and optimize_for_speed parameters/generics in the MegaWizard-generated file. In addition, create and define a value for lpm_widthu for the SCFIFO instance. Here is an example of modified code inside a VHDL MegaWizard-generated output file: COMPONENT scfifo GENERIC ( ALLOW_RWCYCLE_WHEN_FULL: STRING := "OFF"; ALMOST_EMPTY_VALUE: NATURAL := 0; ALMOST_FULL_VALUE: NATURAL := 0; LPM_NUMWORDS: NATURAL; LPM_SHOWAHEAD: STRING := "OFF"; lpm_width: NATURAL; lpm_widthu: NATURAL; -- Altera edit --MAXIMIZE_SPEED: NATURAL := 5; -- Altera edit --OPTIMIZE_FOR_SPEED: NATURAL := 5; -- Altera edit OVERFLOW_CHECKING: STRING := "ON"; UNDERFLOW_CHECKING: STRING := "ON"; USE_EAB: STRING := "ON"; lpm_type: STRING := "scfifo" ); and scfifo14 : scfifo GENERIC MAP ( LPM_NUMWORDS => 3, LPM_SHOWAHEAD => "OFF", lpm_width => 32, lpm_widthu => 2, -- Altera edit OVERFLOW_CHECKING => "ON", UNDERFLOW_CHECKING => "ON", USE_EAB => "OFF) This problem has been fixed in the Quartus II software version 4.0 SP1.
