Operator CMP_AleB

Operator Library: Logic

The operator CMP_AleB (compare A less or equal B) sets the output to a logical "1" if the value at the input link A is less or equal to the value at the input link B, otherwise the output is "0".

To compare the value of input A with a dynamic parameter value use operator IS_LessEqual instead.

Parameters

ImplementationType
Type static write parameter
Default AUTO
Range (AUTO, EmbeddedALU, LUT)

Parameter ImplementationType allows you to influence the implementation of the operator, i.e., to define which logic elements are used for implementing the operator.

You can select one of the following values:

AUTO: When the operator is instantiated, the optimal implementation strategy for the given FPGA architecture is selected automatically, based on the parametrization of the operator.

EmbeddedALU: The operator uses embedded ALU elements of the FPGA.

LUT: The operator uses the LUT elements of the FPGA.

[Note] Use AUTO in General

Normally, the parameter should be set to AUTO. In special cases, i.e., if one kind of FPGA ressource runs short in a design, you can manually influence the FPGA resource management using the values EmbeddedALU and/or LUT.
