Connecting the Blocks

Below are the connection details between blocks for the project:

clock_20_hz

• Input:

• clock: Connected to the system clock input pin clk.

• Output:

• out: Connected to the input of the pulse_count_8_bits block.
  

pulse_count_8_bits

• Input:

• pulse: Connected to the output of clock_20_hz.

• Output:

• counter[7:0]: Connected to the duty_cycle input of the pwm_control8 block.
  

pwm_control8

• Inputs:

• clock: Connected directly to the system clk pin.

• duty_cycle[7:0]: Comes from the output of pulse_count_8_bits.

• Output:

• pwm: Connected to the A input of the inverterC block.
  

inverterC

• Input:

• A: Receives the PWM signal from pwm_control8.

• Output:

• Q: Connected to the output pin l1, which can control an LED.

At the end, your project should be something like this:
