Firstly sorry for my English, I used a translator.
I'm trying to declare a variable SIGNED , plus modelsim returns me the following error: "(vcom-1078) Identifier "signed" is not directly visible." library ieee ; use ieee.std_logic_1164.all ; use ieee.std_logic_arith.all ; use ieee.std_logic_unsigned.all ; use ieee.std_logic_signed.all ; ENTITY test IS PORT( clk : in std_logic; saida : out sfixed(5 downto -20) -- double ); END test; ARCHITECTURE comportamento OF test IS signal B_signed : signed (3 downto 0) ; begin end comportamento; att, Joao PedroLink Copied
