以下是源程序，高手帮忙看向时序或其他哪里有错的，我怎么调写到sram的数据都不对
process(CLK,keyget)
begin
if CLK'event and CLK='1' then
case state is
when st0 =>
if keyget='0' then LED<='1';state <= st1;
else state<=st0;RAM_CS<='1';RAM_WE<='1';RAM_OE<='1';LED<='0'; count<=0;temp<="00000000";
end if;
when st1 =>
if addr="111111111111111" then LED<='0';state <= st0;else addr<=addr+1;temp<=temp+1;state<=st2; --判断是否写完，写完转重录
end if;
when st2 => state <= st3;RAM_CS<='0'; --向ram写数据
when st3 => state <= st4;RAM_WE<='0';
when st4 => state <= st5;dataout<=temp;
when st5 => state <= st6;dataout<=temp;
when st6 => state <= st7;dataout<=temp;
when st7 => state <= st8;dataout<=temp;
when st8 => state <= st9;RAM_WE<='1';
when st9 => state <= st1;RAM_CS<='1';
END CASE;
END IF;
END PROCESS;
