我想问一下关于VHDL语言的问题
if pid_int_reg='1' and pid_int='0' thenint_next<='1';
-- delay register --
t_div_late <= v_error_KD & t_div_late(0 to iDelayD - 2);
-- difference between samples --
v_div <= conv_std_logic_vector(signed(v_error_KD) - signed(t_div_late(iDelayD - 1)) , iDataWidith);
-- integration of error --
v_acu <= conv_std_logic_vector(signed(v_error_KI) + signed(v_acu_earl) , iDataWidith);
-- sum of N - 1 samples of error --
v_acu_earl <= v_acu; then后面的语句是什么执行顺序? then后面的语句是什么执行顺序?

并行 顺序执行,谢谢
