Operator IS_GreaterThan

The operator IS_GreaterThan sets the output to a logical "1" if the value at the input link I is greater than the value of parameter Number, otherwise the output is "0".

To compare the values of two input links use operator CMP_AgtB instead.

Parameters

Number
Type static/dynamic read/write parameter
Default 0
Range same as range of input link I

Value to compare the input link value with.

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 the 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.
