It has to be a joke that you posted it on the science forum of all places.

flatearth,

I too love science (I loved fluid mechanics).
I love testable science.
I love empirical science.
I hate pseudoscience.

There are those who believe they can bring into existence what they imagine.
On the other hand, there are those who don't even believe other people exist: they think their mind is the one forming images and that others are part of their mind.
As for me, I am intelligent and I believe in God.
Water did not create itself.
Let me hear from atheists who think water created itself.

flatearth,

Sorry. I forgot to end with "The earth is flat classroom students!"

DigitalNirvana,

I have a friend, who is a carpenter. I swear he can imagine a beautiful wooden cabinet, and with some hours of work with right tools and materials, honest, he can bring it into existence. It’s amazing!

You might find packets of stevia on restaurant tables and store shelves. Stevia can also be found in many other products you eat. If you’re eating products marketed as low calorie, check the ingredients list to see what type of sweetener was used.
Currently, there’s no evidence linking stevia to cancer when used in normal amounts. Some research suggests it may even have some health benefits. A number of studies stress the need for more research into the potential benefits and risks of stevia.

Stevia may interact with drugs intended to treat hypertension and diabetes.
In animal studies, stevia didn’t affect fertility or pregnancy outcomes, but research on humans is lacking. If you’re pregnant or breastfeeding, stevia glycoside products may be consumed in moderation. Steer clear of whole-leaf stevia and crude stevia extracts while pregnant or nursing.
#Stevia #kombucha #ikombucha_ro #ikombucha

Stevia made with Reb-A is safe to use in moderation during pregnancy. If you’re sensitive to sugar alcohols, choose a brand that doesn’t contain erythritol.
Whole-leaf stevia and crude stevia extract, including stevia you’ve grown at home, are not safe to use if you’re pregnant.
It may seem strange that a highly refined product is considered safer than a natural one. This is a common mystery with herbal products.

Stevia, a zero-calorie sugar substitute, is recognized as safe by the Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). In vitro and in vivo studies showed that stevia has antiglycemic action and antioxidant effects in adipose tissue and the vascular wall, reduces blood pressure levels and hepatic steatosis, stabilizes the atherosclerotic plaque, and ameliorates liver and kidney damage. The metabolism of steviol glycosides is dependent upon gut microbiota, which breaks down glycosides into steviol that can be absorbed by the host. In this review, we elucidated the effects of stevia's consumption on the host's gut microbiota. #Stevia #kombucha #ikombucha_ro #ikombucha
https://pubmed.ncbi.nlm.nih.gov/35456796/

A 2019 study reported a possible link between nonnutritive sweeteners, including stevia, and disruption in beneficial intestinal flora. The same study also suggested nonnutritive sweeteners may induce glucose intolerance and metabolic disorders.
As with most nonnutritive sweeteners, a major downside is the taste. Stevia has a mild, licorice-like taste that’s slightly bitter. Some people enjoy it, but it’s a turn-off for others.
In some people, stevia products made with sugar alcohols may cause digestive problems, such as bloating and diarrhea.

Stevia is considered a "natural non-caloric sweetener." Saccharin and sucralose are considered "non-nutritive sweeteners" (few or no calories). Aspartame is a "nutritive sweetener" (adds some calories but far less than sugar).
Aspartame comes with a warning to be used cautiously (or not at all) by people with a rare genetic disease (called phenylketonuria, or PKU) because they have trouble metabolizing it; that's not true for the other sweeteners. And all four vary on their level of sweetness and aftertaste, which is likely why people often prefer one over another.

Hi, I'm not quite sure if this vhdl code and testbench is correct for the given task. Can you take a look?

Design a one-hour kitchen timer. The device should have buttons/switches to start and stop the timer, as well as to set the desired time interval for the alarm. Realize the task using the software package Quartus or in GHDL, confirm the correctness of the project task by simulation.

This is VHDL code:

use ieee.std_logic_1164.all;
use ieee.numeric_std.all;

entity Kitchen_Timer is
  port (
    clk   : in std_logic;    -- Clock input
    reset : in std_logic;    -- Reset input
    start : in std_logic;    -- Start button input
    stop  : in std_logic;    -- Stop button input
    alarm : out std_logic    -- Alarm output
  );
end entity Kitchen_Timer;

-- Declare the architecture for the kitchen timer
architecture Behavioral of Kitchen_Timer is
  signal count     : integer range 0 to 3600 := 0;   -- Counter for timer
  signal alarming  : std_logic := '0';               -- Signal to indicate alarming interval
  signal alarm_en  : std_logic := '0';               -- Signal to enable alarming interval
  signal alarm_cnt : integer range 0 to 600 := 0;    -- Counter for alarming interval
begin
  -- Process to control the kitchen timer and alarming interval
  process (clk, reset)
  begin
    if (reset = '1') then
      count     <= 0;
      alarming  <= '0';
      alarm_en  <= '0';
      alarm_cnt <= 0;
    elsif (rising_edge(clk)) then
      if (stop = '1') then
        count     <= 0;
        alarming  <= '0';
        alarm_en  <= '0';
        alarm_cnt <= 0;
      elsif (start = '1' and count < 3600) then
        count <= count + 1;
        if (count = 3600) then
          count     <= 0;
          alarming  <= '0';
          alarm_en  <= '0';
          alarm_cnt <= 0;
        elsif (count > 0) then
          alarm_en <= '1';
        end if;
      end if;

      if (alarm_en = '1') then
        if (alarm_cnt < 600) then
          alarm_cnt <= alarm_cnt + 1;
        else
          alarm_cnt <= 0;
          alarming  <= '1';
        end if;
      end if;
    end if;
  end process;

  -- Assign the alarm output
  alarm <= alarming;
end architecture Behavioral; ```


This is Testbench:

```library ieee;
use ieee.std_logic_1164.all;

entity tb_Kitchen_Timer is
end tb_Kitchen_Timer;

architecture tb of tb_Kitchen_Timer is

    component Kitchen_Timer
        port (clk   : in std_logic;
              reset : in std_logic;
              start : in std_logic;
              stop  : in std_logic;
              alarm : out std_logic);
    end component;

    signal clk   : std_logic;
    signal reset : std_logic;
    signal start : std_logic;
    signal stop  : std_logic;
    signal alarm : std_logic;

    constant TbPeriod : time := 1000 ns; -- EDIT Put right period here
    signal TbClock : std_logic := '0';
    signal TbSimEnded : std_logic := '0';

begin

    dut : Kitchen_Timer
    port map (clk   => clk,
              reset => reset,
              start => start,
              stop  => stop,
              alarm => alarm);

    -- Clock generation
    TbClock <= not TbClock after TbPeriod/2 when TbSimEnded /= '1' else '0';

    -- EDIT: Check that clk is really your main clock signal
    clk <= TbClock;

    stimuli : process
    begin
        -- EDIT Adapt initialization as needed
        start <= '0';
        stop <= '0';

        -- Reset generation
        -- EDIT: Check that reset is really your reset signal
        reset <= '1';
        wait for 100 ns;
        reset <= '0';
        wait for 100 ns;

        -- EDIT Add stimuli here
        wait for 100 * TbPeriod;

        -- Stop the clock and hence terminate the simulation
        TbSimEnded <= '1';
        wait;
    end process;

end tb;

-- Configuration block below is required by some simulators. Usually no need to edit.

configuration cfg_tb_Kitchen_Timer of tb_Kitchen_Timer is
    for tb
    end for;
end cfg_tb_Kitchen_Timer;```

@dejo

can you send me the code with the modifications so that I know what exactly you mean?

I would rather not, as it isn't a good learning experience for you, and would require some time for me to write the code.

Though if you have any questions about my previous answer, feel free to ask me about it.

As a freebie for you, pay attention to the alarming signal, and the condition that has been set: "The device should have buttons/switches to start and stop the timer, as well as to set the desired time interval for the alarm.". If I wanted the alarm to ring after 50 minutes, how would I do that? And what happens when the timer starts?

From the code I see here, the alarm is going to ring 10 minutes after being started, and it won't stop until an hour passes. And it has no way to set a time for it to ring, it always rings after 10 minutes.

And, not only that, the start signal is never set in the testbench, so the timer is never going to begin.

T4V0,

@dejo

What do you think about the specifications that the project requires, should I stick to your code or should I add something from my own code?

I would stick to my code, your alarm isn't going to work properly due to its comparisons as I mentioned in my previous comments. But if you want to improve the code I modified, you can change the adjust_interval_up and adjust_interval_down buttons to be synchronized to their own states rather than the clock (make their own process with their signals added to the signal sensitivity list and add an extra asynchronous condition to zero the counter on the original process). If you don't make a change like this your alarm is going to take up to an hour to adjust its timer range.

Does your simulation correspond to a time of 1 hour and should there be alarming on the simulation?

Yes, if you have a 1/60 Hertz clock signal. And you must have alarming on the simulation as it is crucial to show that it works.

The US is investing more than $1 billion in carbon capture, but big oil is still involved: 1PointFive is helping oversee one plant in Texas. It also has direct ties to one of the world's largest fossil fuel producers.
https://www.popsci.com/environment/carbon-capture-plants-doe/

Knusper,

“1PointFive’s mission is to reduce atmospheric CO2 and help curb global temperature rise to 1.5°C by 2050 in alignment with Paris Agreement targets,”

Fucking hell, when even your organisation name is propaganda. This is what would need to happen for that +1.5°C target:

Projection for Global Warming showing that the +1.5°C target would require halving emissions until 2030.

No credible scientist still believes in us hitting that. Not the optimistic ones either.
