Did you know?
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'.

WebA generic map gives the value to a generic. Usually given in an instance but can also appear in a configuration. The values can be given via positional association or via named association. Use of named association is advised to improve readability and reduce the risk of making errors. Web1 day ago · I then convert to std logic vector using signal R: std_logic_vector((N*(2**M))-1 downto 0); I then convert and port map using a for generate function. This is done because the port map only allows for mapping of type std_logic_vector for Q as indicated by the component my_rege.
