Using Conversion Functions (VHDL) CONV_STD_LOGIC_VECTOR--Converts a parameter of type INTEGER, UNSIGNED, SIGNED, or STD_LOGIC to a STD_LOGIC_VECTOR value with SIZE bits. The Compiler adds zeros to the MSBs for UNSIGNED values and uses sign- extension for SIGNED values.

Arrays are used in VHDL to create a group of elements of one data type. Arrays can only be used after you have created a special data type for that particular array. Below are some rules about arrays. Arrays can be synthesized; Arrays can be initialized to a default value I think if it was me, and since the data in this case is just a vector with no direct meaning (as in, it is not a signed or unsigned number), I would make std_center_height have a width of C_S_AXI_DATA_WIDTH, so that it could be connected to the instantiation in a 'normal' way.I would then only use the constant that defines the width of std_center_height when using this vector.

I read many manuals but i don't know about right technics about work with arrays in VHDL. I use Quartus II 13.0. Underwritten simple example don't compile without er Arithmetic on std_logic_vector. VHDL has a well-designed package IEEE.Numeric_Std which creates two new data types unsigned and signed. However it would sometimes be convenient to do arithmetic on std_logic_vector directly - treating it as either two's complement or unsigned.

Hello, I'd like to assign a value to an std_logic_vector, and fill the rest of the vector with zeros. The length of the vector is defined with a generic or a constant. So it would be like this (but this does not work): signal my_signal : std_logic_vector(CONST_WIDTH downto 0); my_signal <= (others => '0') & x"2"; It could be done with a for
