Build a circuit with no inputs and one output. That output should always drive 1 (or logic high).

这是一个技术问题,我可以回答。您可以使用一个简单的电路,将输出与电源直接连接。例如,您可以使用一个电源来提供3V电压,然后使用一个晶体管或继电器将输出引脚连接到电源引脚。这样,输出引脚将始终保持高电平,因为电路的电路图仅包括输出和电源,没有任何干扰量或输入信号。

• Write a python code that find all the prime number in a int list. • Test your code with different inputs.
Here's a Python code that finds all the prime numbers in a given integer list:
```python
def is_prime(num):
if num < 2:
return False
for i in range(2, int(num ** 0.5) + 1):
if num % i == 0:
return False
return True
def find_primes(lst):
return [num for num in lst if is_prime(num)]
# Test the function
lst1 = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
lst2 = [17, 19, 20, 23, 28, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]
lst3 = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15]
print(find_primes(lst1)) # Output: [2, 3, 5, 7, 11, 13]
print(find_primes(lst2)) # Output: [17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97]
print(find_primes(lst3)) # Output: [2, 3, 5, 7, 11, 13]
```
The `is_prime()` function checks whether a given number is prime or not. It returns `True` if the number is prime, and `False` otherwise. The `find_primes()` function takes a list of integers as input and returns a list of prime numbers in that list.
In the test cases, we have used three different lists with different integer values. The output shows the prime numbers present in these lists.
You are given a module my_dff with two inputs and one output (that implements a D flip-flop). Instantiate three of them, then chain them together to make a shift register of length 3. The clk port needs to be connected to all instances. The module provided to you is: module my_dff ( input clk, input d, output q ); Note that to make the internal connections, you will need to declare some wires. Be careful about naming your wires and module instances: the names must be unique.
Here is the code to instantiate three my_dff modules and chain them together to make a shift register of length 3:
```
module shift_register ( input clk, input in, output out );
wire q1, q2, q3;
// Instantiate three my_dff modules
my_dff dff1(clk, in, q1);
my_dff dff2(clk, q1, q2);
my_dff dff3(clk, q2, q3);
// Output the last value of the shift register
assign out = q3;
endmodule
```
In this code, we declare three wires `q1`, `q2`, and `q3` to connect the output of each `my_dff` module to the input of the next. We then instantiate three `my_dff` modules, connecting the `clk` input to all of them, and connecting the output of the first to the input of the second, the output of the second to the input of the third, and the output of the third to the `q3` output of the `shift_register` module.
Note that the input to the `shift_register` module is named `in` to avoid conflict with the `input` keyword.
