Can't set LPM_SHOWAHEAD parameter to ON for a FIFO buffer in Stratix devices


CAUSE: You set the LPM_SHOWAHEAD parameter of a FIFO buffer to ON; however, Stratix devices cannot contain a FIFO buffer with the LPM_SHOWAHEAD parameter set to ON. This error usually occurs when you instantiate a megafunction directly in a text file rather than using the MegaWizard Plug-In Manager command.
ACTION: Modify the design so that LPM_SHOWAHEAD parameter is set to OFF. To avoid receiving this message in the future, Altera recommends using the MegaWizard Plug-In Manager command.
