PWM Code to for mosfet gate

i tried another code with timer 0 and trying to adjust OCR0A&B values to change the freq of the pulses and i am using proteus simulator the frequency is not changed whatever i do and const at 62KHz

#define dute_cycle 40

void setup() {
  // Set pins 5 and 6 as output
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  
  // Configure Timer0 for Fast PWM mode
  TCCR0A = (1 << COM0A1) | (1 << COM0B1) | (1 << WGM01) | (1 << WGM00);
  TCCR0B = (1 << CS00);  // No prescaler

  // Set TOP value for desired frequency (30 kHz)
  // Formula: TOP = (F_CPU / (N * desired frequency)) - 1
  // For Arduino Nano (16 MHz), N = 1
  OCR0A = 105;  // TOP value for pin 5 (16 MHz / (1 * 30 kHz) - 1)
  OCR0B = 105;  // TOP value for pin 6 (16 MHz / (1 * 30 kHz) - 1)
}

void loop() {
  // Adjust duty cycle if needed
  // Example: 50% duty cycle for both pins
  analogWrite(5, (dute_cycle * 255) / 100);
  analogWrite(6, 128);
}

Do you have any idea what is happening?
