1. The voltage divider (for the sake of this simulation, the voltage is directly taken) 2. 3-bit Flash type ADC to convert that voltage level into digital output 3. A 8x3 priority encoder to convert the ADC output to binary code 4. A PIPO to send data from the encoder to lcd every clock cycle 5. LCD interfacing…
