WebBruce, How do you handle it when your signals are not std_logic_vector(0 downto 0) but rather standard_logic? VHDL is very strict on this sort of thing. I would like it to work out so that the actual signal names are visible in the Hardware Manager. In other words I want them to be RxBit_slv for example. 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.
