Port maps in vhdl

WebMay 16, 2024 · As VHDL is a strongly typed language, the signals we use in the port map must also match the type of the port they connect to. When we write VHDL code, we may also wish to leave some ports unconnected. For example, we may have a component which models the behaviour of a JK flip flop. Webport map ( center_height => std_center_height ); some_other_vector <= std_center_height (C_STD_CENTER_HEIGHT_WIDTH-1 downto 0); Note that some_other_vector is not an alias of std_center_height, but is just used as an example of 'making use of std_center_height in some other bit of logic'.
