architecture behav of test1 is type my_state is(state1,state2); signal p_state,n_state:my_state; signal n:integer range 0 to 10; begin process(p_state,hf1) begin case p_state is when state1 => n<=0; dataout<="00000000"; if(hf1='0') then n_state<=state2; else n_state<=state1; end if; when state2 => dataout<=datain1; n<= n + 1; if(n = 10) then n_state<=state1; else n_state<=state2; end if; when others => null; end case; end process; process(rst,clk) begin if(rst='1') then p_state<=state1; elsif(clk='1' and clk'event) then p_state<=n_state; end if; end process; end behav; 本意想在状态为state2时，把10个输入送给输出，然后又回到state1 结果仿真的时候，发现在state2情况下，n并不是在每个时钟 的上升沿递增，而是一系列很乱的数字，象毛刺似的，状态也就一直 处于state2下，但小弟我实在看不出程序哪儿有问题，请教大虾 我用的是max＋plus2 10.0版本 谢谢
