In your case you are treating a std_logic_vector (0 downto 0) as if it were a std_logic. You cannot compare a std_logic_vector to a '1' or '0' value, however you can compare or assign one bit of the vector (even if it only has one bit) to '1' or '0' or you co...
先将INTEGER根据需求使用 to_signed(interger,signed'length) 转为 SIGNED 或者使用 to_unsigned(integer,unsigned'length) 转为UNSIGNED，然后使用STD_LOGIC_VECTOR(signed/unsigned)转为整数。例:https://www.nandland.com/vhdl/examples/example-signed-unsigned.html ...
在VHDL中,将integer类型转换为std_logic类型涉及几个步骤,因为std_logic是一个单比特的逻辑值,而integer可以是多比特的整数。为了将integer转换为std_logic,我们通常需要考虑integer的某一位(例如最低位)或者根据条件决定std_logic的值(例如,integer是否为0)。 以下是一个详细的步骤说明和示例代码,展示如何将integer转...

conv_integer（变量） 转换回来是conv_std_logic_vector(变量，位数）
I'm new to VHDL and I am trying to convert an integer to a 14 bit vector. Here is the protion of my code. gear_calc <= to_integer(unsigned(to_stdlogicvector(Input_2))); synchro_gear <= gear_calc*36; IF synchro_gear < 360 THEN FOR i IN 0 to 16383 LOOP synchro_...
