3.8. Control File Generation Dynamically with Parameters and a Fileset Callback

You can use a fileset callback to control which files are created in the output directories during the generation phase based on parameter values, instead of providing a fixed list of files. In a callback procedure, you can query the values of the parameters and use them to generate the appropriate files. To define a fileset callback, you specify a callback procedure name as an argument in the add_fileset command. You can use the same fileset callback procedure for all of the filesets, or create separate procedures for synthesis and simulation, or Verilog and VHDL.

Fileset Callback Using Parameters to Control Filesets in Two Different Ways

The RAM_VERSION parameter chooses between two different source files to control the implementation of a RAM block. For the top-level source file, a custom Tcl routine generates HDL that optionally includes control and status registers, depending on the value of the CSR_ENABLED parameter.

During the generation phase, Platform Designer creates a top-level Platform Designer system HDL wrapper module to instantiate the component top-level module, and applies the component's parameters, for any parameter whose parameter property HDL_PARAMETER is set to true.
