Parameters Tab (Qsys Pro Component Editor)

You access this tab in the Qsys Pro Component Editor by clicking the Parameters tab.

In a non-HDL based flow (when you do not have your own HDL file), the Parameters tab allows you to add Verilog HDL and VHDL parameters to your component. The following settings affect the parameterization GUI that Qsys Pro creates for your component in a Qsys Pro system:

  • Parameters table—Allows you to view and specify the Verilog HDL parameters or VHDL generics for each interface as follows:
  • Name—Specifies a unique name for your parameter.
  • Default value—Specifies the default value of the parameter displayed in the GUI.
  • Editable—Turning on this option enables user editing of the parameter in the GUI.
  • Type—Specifies the type of parameter as string, integer, boolean, std_logic, logic vector, natural, or positive.
  • Group—Specifies the parameter group name.
  • Tooltip—Specifies the tooltip text that is displayed in the GUI.
  • Parameter buttons—Allow you to perform the following functions:
  • Add Parameter—Creates a default new_parameter in the Parameters table.
  • Remove Parameter—Deletes selected parameter in the Parameters table.
  • Preview the GUI—Displays the current state of the generated GUI.
Note: When you have already created an HDL file, you must include the parameters in the top-level HDL file in order for the parameters to appear in the Parameters table.
