I suppose this is very basic question - sorry about that. The error I get: "std_logic_vector" is used but not declared ... but I thought, that is done by the use statement ... library ieee; use ieee.std_logic_1164.all; entity eq1 is port( i0, i1: in std_log...
将USE IEEE.STD_LOGIC_1164; 改成USE IEEE.STD_LOGIC_1164.ALL;
function BadDefault_f(B: std_logic_vector := (0 => '0', others => std_logic'left)) return std_logic_vector is if the intention is to assign to only 0th element. --dhiRAj Expand Post LikeReply ilewis (Member) 9 years ago Hello dhiRAj...
you declared un as an integer but assigned a bit to it. I think you should remove the single quotation marks around the 0. --- Quote Start --- if (un <= 9) then -- check if units is less than or equal to 9 --- Quote End --- I think this should...
Signal Slv2 was declared using an initial value of all 0’s. Instead of specifying the exact value for each bit, we used (other => '0') in place of the initial value. This is known as an aggregate assignment. The important part is that it will set all bits in the vector to whate...
In the example above, the subb_0014 sub block has 2 ports of type bit_vector. The component subb_0014 declared in the ex_0014 has 2 ports of a different type: std_logic_vector. This is not a VHDL LRM compliant code. To solve this issue, align the entity and component port types. ...

If you find that division is not performed in your code, then check if there is some optimizations. Before that, check if you have declared the range on the integer signals appropriately. Is it possible to get the complete code, if you feel everything is alright in the design? Upvote 0...
