Counter Concepts The general idea behind the counter is pretty simple: Start at some initial count value and store it in a register. Increment the counter. Save the new count value back into the register. The counters that I’m going to implement for you in this VHDL counter example count backwards and forwards from/to 12. It may sound strange, but I have a very good reason for counting backwards, and I’ll get into that in the Synthesis Considerations section. This counter has an ability to load a custom value to start counting down or up from which is neat. I added the ability to speed up or slow the clock. An up/down counter is written in VHDL and implemented on a CPLD. The VHDL while loop as well as VHDL generic are also demonstrated. Four different VHDL up/down counters are created in this tutorial: Up/down counter that counts up to a maximum value and then wraps around to 0. Torrent download free.

After all, it’s just as easy to compute x-1 as it is to compute x+1. The code example implements a 5-bit counter that counts backwards, and two 4-bit counters that count forward–one of which is allowed to free run. 00101 (5) 00100 (4) 00011 (3) 00010 (2) 00001 (1) 00000 (0) 11111 (31) Using this method, we can just watch for the MSB to be equal to 1 to see if we’re done counting. That’s a single logic operation no matter how wide the count register is! Typical Uses Counters are used in almost every logic design. Fundamentally, they’re the only way to keep track of time in an FPGA, and the uses are endless. A few examples are keeping track of packet sizes when sending data in a protocol, response timeouts, physical button debouncing, etc. Happy coding! We want to hear from you! Do you have a comment, question, or suggestion? Feel free to drop us an email or post a comment. I am trying to make a four bit up/down modulo10 counter. Button1 - counts up, Button2 - counts down. I'm trying to do it using rising_edge command but for two signals I can’t define with button was pressed. So in next version of program I want detect button using if statement. Library IEEE; use IEEE.std_logic_1164.all, IEEE.numeric_std.all; ENTITY counter is generic (n:natural:=4); port( button1: in std_logic; button2: in std_logic; clear: in std_logic; C: out std_logic; OUT1: out std_logic_vector(n-1 downto 0) ); END counter; ARCHITECTURE beh of counter is begin p0:process (button1, clear) is variable count: unsigned (n-1 downto 0); begin if clear = '1' then count:= (others=>'0'); elsif button1='1' then count:=count+1; elsif count=10 then count:=(others=>'0'); C'1'); C. Vhdl Program For 8 Bit AluYou should use a CLOCK signal to use rising_edge, I created a clock signal in your entity: clock: in std_ulogic; After this you should put in your process sensitivy the CLOCK signal and the button2 signal, like this: p0:process (button1, button2, clear, clock) is My simulation with this conditions work correctly, when I press button1 the count goes up, when I press button2 count goes down. The complete architecture: ARCHITECTURE beh of counter is begin p0:process (button1, button2, clear, clock) is variable count: unsigned (n-1 downto 0); begin if rising_edge(clock) then if clear = '1' then count:= (others=>'0'); end if; if (button1='1') then count:=count+1; elsif (count=10) then count:=(others=>'0'); C'1'); C. 8 Bit Brewery MurrietaCreative inspire 5.1 5300 driver windows 7.
