我收到此错误:
# Error: COMP96_0100: data_reg.vhd : (156, 35): Actual parameter type in port map does not match the port formal type "Allin".
# Error: COMP96_0100: data_reg.vhd : (158, 1): Actual parameter type in port map does not match the port formal type "Fout".
# Error: COMP96_0100: data_reg.vhd : (162, 1): Actual parameter type in port map does not match the port formal type "D".
# Error: COMP96_0100: data_reg.vhd : (163, 1): Actual parameter type in port map does not match the port formal type "Q".
我需要一些帮助。

答案 0 :(得分:1)
您应该仔细阅读一些初学者的VHDL指南。我不能推荐任何人(也许有人可以?),所以我会直接回答你的错误:
std_logic_unsigned
,std_logic_unsigned
和std_logic_arith
。此库不是标准的一部分,可以用numeric_std
替换。bit
或bit_vector
类型。请改用std_logic
和std_logic_vector
。std_logic_vector(7 downto 0)
分配给bit_vector(3 downto 0)
。这里可能有更多错误,但你的问题并不完整 - 你没有提供任何解释它应该做什么,没有完整的代码,也没有测试平台。
