WebDec 11, 2024 · The most straightforward way to create a shift register is to use vector slicing. Insert the new element at one end of the vector, while simultaneously shifting all of the others one place closer to the output side. Put the code in a clocked process and tap the last bit in the vector, and you have your shift register. 1. WebMay 4, 2016 · The entity “clock_div” should be instantiated as a component in your VHDL design. When you will instantiate the component you have to set the input port. “i_clk_divider : in std_logic_vector (3 downto 0);”. with the value 5 because you need to divide your 50MHz clock by 5 to get the 10 MHz clock. for instance:

(On the other hand, using int for generics, some constants, and some variables can be highly useful.) Simply put, if you declare a signal of type int, or have to specify a range for an integer then you're probably doing something wrong. ovenstory pizza tagline
