Subprograms in VHDL

Description

I received the following error message when I was trying to compile a VHDL file. What I can do to fix it?

Error: COMP96_0321: C:/../<File_Name>.vhd : Subprogram specification of the body must conform to the subprogram specification of the declaration.

Solution

There are two solutions:

1. Please use -relax switch to allow compile files which not follow strictly the LRM:

   Example:
   acom -relax …
   

   ...

2. Or you can correct the subbrogram declaration:

   • On package body exist:

   • function <Function_name> (in_value : in integer) return string

   • On package declaration:

   • function <Function_name> (in_value : integer) return string

   • Please update the package declaration for:

   • function <Function_name> (in_value : in integer) return string
