The following AHDL function prototype is located in the AHDL Include File (.inc) Definitionlpm_dff.inc in the < Quartus® Prime installation directory>\libraries\megafunctions directory.
FUNCTION lpm_dff (data[LPM_WIDTH-1..0], clock, enable,
shiftin, shiften,
sclr, sset, sconst,
aclr, aset, aconst)
WITH (LPM_WIDTH, LPM_AVALUE, LPM_SVALUE)
RETURNS(q[LPM_WIDTH-1..0], shiftout);
