          occur during compilation, then the RDLCompiler object should be discarded.
  
          Parameters
          ----------
          path:str
              Path to an RDL source file
  
          incl_search_paths:list
              List of additional paths to search to resolve includes.
              If unset, defaults to an empty list.
  
              Relative include paths are resolved in the following order:
  
              1. Search each path specified in ``incl_search_paths``.
              2. Path relative to the source file performing the include.
  
          Raises
          ------
          :class:`~systemrdl.RDLCompileError`
              If any fatal compile error is encountered.
