    typeL = HDLRuby::Low::Type.new(name)
    # # For debugging: set the source high object 
    # typeL.properties[:low2high] = self.hdr_id
    # self.properties[:high2low] = typeL
    return typeL
end

#to_rcsim ⇒ Object

Generate the C description of the type comming from object whose C description is +rcowner+. NOTE: +rcowner+ is not used here.
