However these shift operators never worked correctly and were removed from the Unfortunately VHDL doesn't have this operator. According to the comp.lang.vhdl FAQ, though . There is no predefined VHDL operator to perform a reduction operation on all bits of vector (e.g., to "or" all bits of a vector). 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.

HDL Code Generation Generate Verilog and VHDL code for … If you're serious about testing a std_logic_vector against an integer type you can write an equality operator Vhdl - Std logic vector in VHDL compare with zero and other vector Menu 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 VHDL Partially Initialize in 0 a vector array Im trying to create an array of vectors like shown in the code below: type ram256 is array (0 to 255) of std_logic_vector (11 downto 0); signal memoria: ram256; The problem is that, initially i only use about the first 25 vectors of the type.
So if you are checking that all bits in the bus are zero, then use the and_reduce, or when VHDL 2008 gets support, you can just write the following: if (and my_slv) then. But if your std_logic_vector represents a number, compare it to the integer 0. if my_slv = std_logic_vector (to_unsigned (0, my_slv'length)) then
During the declaration the size of a vector is specified. 2010-02-06 · What's the correct vhdl coding technique to initialize it without reading from a file?
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
VHDL has the concept of unconstrained data types, which means that the range of an array or vector is not declared in the type.
To check if the vector contains all zeros: unsigned(my_slv) = 0 The statement above yields a true value if the vector contains only '0' or 'L':

Please how can I write a statment in VHDL to zero pad an std_logic_vector from the left. for example I have X defined as std_logic_vector(XMAX -1 downto 0) and Y defined as std_logic_vector(YMAX -1 downto 0) and XMAX = 32 and YMAX = 64 . if I want to make zero padding to Y from the right I use this statment . Y <= X & (others => '0');
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 generate statement, but are there any shorter and nicer solutions?
