the denom[] input as signed two's

complement.

LPM_TYPE String No Identifies the library of parameterized

design files (.vhd).

LPM_HINT String No

When you instantiate a library of

parameterized modules (LPM)

function in a VHDL Design File (.vhd)

, you must use the LPM_HINT

parameter to specify an Altera-specific

parameter. For example: LPM_HINT =

"CHAIN_SIZE = 8, ONE_INPUT_IS_

CONSTANT = YES"
