Just stumbled upon this one

50$ for the 50k gate version

Ok. I decide to try Actin HDL (student edition). I made basic code. How can I test it? I can't find good tutorial on google.
You can test it by making a testbench. See this here tutorial.

Can you give me VHDL test bench for (I called my first project test):

library IEEE;
use IEEE.STD_LOGIC_1164.all;

entity test is
    port(
        sw0 : in STD_LOGIC;
        sw1 : in STD_LOGIC;
        LED0 : out STD_LOGIC;
        LED1 : out STD_LOGIC
        );
end test;

architecture test of test is
begin
   LED1 <= sw1;
    LED0 <= sw0;
end test;

I need some periodic signal on sw0 and sw1.

First, you'll need a clock.

I hope this is what you're looking for  ;)
I inserted one clock at 5MHz and another one at 10MHz.

Thank you. Now I can test my code. For few weeks/months that will work and then I will think again about devboard.
