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

When one has something like variable a : unsigned (3 downto 0); variable b : unsigned (1 downto 0); and one wants to assign the lower b'length bits of b to a, is it necesary to do

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 The VHDL keyword “std_logic_vector” defines a vector of elements of type std_logic. For example, std_logic_vector (0 to 2) represents a three-element vector of std_logic data type, with the index range extending from 0 to 2. Let’s use the “std_logic_vector” data type to describe the circuit in Figure 3. In VHDL code it is declared as type "std_logic_vector (0 downto 0)", but for compiler this is not the same as "std_logic", type of signal assigned to this bus.

However, the reduction operators can be easily implemented: [skipping an example that doesn't handle 'X' and 'Z' values] The value of a generic may be read in either the entity or any of its architectures. It may even be passed into lower-level components. Default values for generics may be given in an entity declaration or in a component declaration.generics may be set (via a generic map) in an instantiation, or a configuration.The rules regarding different combinations of these are complex: see "VHDL" by I am a teaching assistant, and was told to write a VHDL, to show the students, for a one-input, two output circuit whose outputs represent the number of ZEROS that have appeared in the last three inputs, and I want to use edgre-triggered D flip-flops in addition to some other logic. But I am 5. 0 VHDL OPERATORS There are seven groups of predefined VHDL operators: 1.

The VHDL code for declaring a vector signal that can hold a byte: signal MySlv : std_logic_vector(7 downto 0); The VHDL code for declaring a vector signal that can hold one bit: signal MySlv : std_logic_vector(0 downto 0); The VHDL code for declaring a vector signal that can hold zero bits (an empty range): signal MySlv : std_logic_vector(-1 downto 0);
