Question
Correct the syntax errors in the following piece of code: library ieee; use ieee.std_logic_1164.all; entity testcode is port(switch: in std_logic; a, b: in std_logic; y: out std_logic;); end; architecture imp of quizcode is begin signal x, x2: std_logic; x lessthanorequalto (not a and b) or (a and not b); -- displays xor gate x2 lessthanorequalto not (a and b); if switch = "0" -- displays switch value and xor gate y(0) lessthanorequalto "0"; y(1) lessthanorequalto x; elsif switch = "1" -- displays switch value and nand gate y(0) lessthanorequalto "1"; y(1) lessthanorequalto x2; --displays all zeroes else y lessthanorequalto "00"; end if; end process; end;Explanation / Answer
library ieee;
use ieee.std_logic_1164.all;
port{
switch:in std_logic;
a,b:in std_logic;
y:out std_logic
};
end:
begin
signal x,x2:std_logic
x<=(not a and b) or (a and not b);
x2<=not(a and b)
if switch="0"
{
y(0)<="0";
y(1)<= x;
}
elseif switch="1"
{
y(0)<="1";
y(1)<= x2;
}
else
{
y<="00"
}
end if;
end process;
