The statement USE IEEE.STD_LOGIC_UNSIGNED.ALL is needed in order to perform subtractions on STD_LOGIC_VECTORs. In VHDL we cannot omit the return value or return void, a function always has to return something and the return value has to be assigned to something.

port(C, CLR : in std_logic; This is because we did not compile counter before counter_sim. When compiling VHDL designs that instantiate entities, the bottom levels must always be compiled before the top levels (hierarchical designs can also be compiled top-down but only if they instantiate component, not entities). The rising_edge function used by our design is not defined. Dec 22, 2020 vhdl counter. I'm trying to understand the description of a counter in VHDL: entity counter is port ( load, reset, clk: in bit; input: in integer range 0 Feb 10, 2013 Counter Concepts.
