not because i'm a VHDL expert because I certainly aren't but because the library function has to cater for every possibility of input std_logic_vector into integer. I could be wrong but I used the following functions to do the conversion.

For verification, it will be easier if you start to think more about integers when the value is less than 32 bits. vhdl type conversion Hi Guys .. I want to convert between the 2 vector types (SIGNED to STD_LOGIC_VECTOR). I used the function 'CONV_SIGNED (ARG:SIGNED, SIZE:INTEGER) return STD_LOGIC_VECTOR;' but it always gives me ZEROs in the returned STD_LOGIC_VECTOR regardless of the value contained in the SIGNED vector!! ..

Vhdl integer to std_logic_vector

To overcome this problem, we must firstly convert the integer to either a signed or unsigned type. Code VHDL - [expand] 1 std_logic_vector (to_unsigned (((to_integer (unsigned (weptr))) + 1), 4)) CONV_STD_LOGIC_VECTOR--Converts a parameter of type INTEGER, UNSIGNED, SIGNED, or STD_LOGIC to a STD_LOGIC_VECTOR value with SIZE bits. Four versions of each function are available; the correct version for each function call is determined through operator overloading. I have trouble understanding conversion between different data types in VHDL and needed help with conversion to `STD_LOGIC_VECTOR' type in VHDL. I want the code below to be synthesized such that it can be used on real hardware. For now i have the code setup as follows Any given VHDL FPGA design may have multiple VHDL types being used. The most common VHDL types used in synthesizable VHDL code are std_logic, std_logic_vector, signed, unsigned, and integer.

Vhdl integer to std_logic_vector

It is quite typical to see the cast and the … 2008-04-13 2013-11-06 The VHDL data are of a specific type such as std_logic, std_logic_vector, bit, bit_vector, or user defined. Std_logic is read as standard logic and std_logic_vector as standard logic vector.

I don't think that you can convert an std_logic to integer, you will probably need to use std_logic_vector signals of a single bit, like: signal names : std_logic_vector(0 downto 0); Reactions: MSAKARIM
