Description
Parameter Name
Specifies the name of the parameter to be passed to the Verilog source code.
When using Define types, be sure to make the name globally unique.
Display Text
Specifies the display text that will be placed adjacent to the specific control. Each
component, when added to the platform, brings up an individualized dialog box.
Each element in the dialog box has descriptive text placed adjacent to a control.
Value Type
Specifies the value type. Choose Define, String, Integer, List, or Frequency from
the drop-down menu.
Default Value
Specifies how each parameter or `define is initialized when a component is
added to the platform. This field is free-form, so you must be careful when
entering default values. Any type mismatch or incorrect data entered here will
impact the synthesis process later.
