UserComment UserComment Specify comment line in header of generated filter and test bench files Settings The coder includes a header comment block at the top of the files it generates. The header comment block contains information about the specifications of the generating filter and about the coder options that were selected at the time HDL code was generated. You can add your own comment lines to the header comment block by setting UserComment to the desired string value. The code generator adds leading comment characters that correspond to the target language. When you include newlines or line feeds in the string, the coder emits single-line comments for each newline. For example, the following generatehdl command adds two comment lines to the header in a generated VHDL file. generatehdl(Hlp,'UserComment','This is a comment line.\nThis is a second line.') The resulting header comment block for filter Hlp would appear as follows: ------------- ------------------------------------------------------------- ------- ------------------------------------------------------------HDL Code Generation Options: ------- Filter Specifications: Module: Hlp Generated by MATLAB(R) 7.11 and the Filter Design HDL Coder 2.7.
