15 years agooops, i posted the wrong version of the FSM code. the only diff is that i have done <= '0' in the n=1 case in state s0. The simulation also works as I expect it to, an image of it is included at the bottom. But if I run the code on a nios II core on the DE0 board, it doesn't work. The results are delayed as described above with the same code.
here's the good version of the code:
PROCESS (reset, clk)
BEGIN
if (reset = '1') then
state <= s0;
ELSIF (clk'EVENT AND clk = '1') THEN
CASE state IS
WHEN s0 =>
IF (start = '1' AND n = '0') THEN
io_148194546 <= dataa;
io_277277265 <= datab;
state <= s0;
done <= '1';
ELSIF (start = '1' AND n = '1') THEN
io_109970892 <= dataa;
io_19111827 <= datab;
state <= s1;
done <= '0';
ELSE
state <= s0;
done <= '1';
END IF;
WHEN s1 =>
result <= io_1298736395;
done <= '1';
state <= s0;
WHEN OTHERS =>
report "Invalid State";
END CASE;
END IF;
END PROCESS;
END behavior;
