Hi
I am trying a full adder design
I need to check if the carry is 1 or 0
cout: out STD_LOGIC;
process (cout)
begin
if ( cout ='0') then
---
---
--
else
--
---
end if;
end process;
it gives me an error that cout is an output and can't be read
How can I test an output signal??even if I try to define a signal and transfer the value of cout to that signal I get the same error
thnx
