6.6. Parameters

The following table lists the parameters for the LPM_COMPARE IP core.

Table 20.  LPM_COMPARE IP core Parameters
Parameter Name Type Required Description
LPM_WIDTH Integer Yes Specifies the widths of the dataa[] and datab[] ports.
LPM_REPRESENTATION String No Specifies the type of comparison performed. Values are SIGNED and UNSIGNED. If omitted, the default value is UNSIGNED. When this parameter value is set to SIGNED, the comparator interprets the data input as signed two's complement.
LPM_PIPELINE Integer No Specifies the number of clock cycles of latency associated with the alb, aeb, agb, ageb, aleb, or aneb output. A value of zero (0) indicates that no latency exists, and that a purely combinational function will be instantiated. If omitted, the default value is 0 (non-pipelined).
LPM_HINT String No Allows you to specify Intel® -specific parameters in VHDL design files (.vhd). The default value is UNUSED.
LPM_TYPE String No Identifies the library of parameterized modules (LPM) entity name in VHDL design files.
INTENDED_DEVICE_FAMILY String No This parameter is used for modeling and behavioral simulation purposes. The parameter editor calculates the value for this parameter.
ONE_INPUT_IS_CONSTANT String No Intel® -specific parameter. You must use the LPM_HINT parameter to specify the ONE_INPUT_IS_CONSTANT parameter in VHDL design files. Values are YES, NO, or UNUSED. Provides greater optimization if an input is constant. If omitted, the default value is NO.
