As a designer what will be your strategies to design sustainable complex circuits?  

VLSI technique

An LED is connected to PD3 and a Button is connected to PD0. Write a C program that will wait for the button to be pressed and then released (make sure you debounce the press and release). Each time the button is pressed, the LED blinks a number of times corresponding to how many times the button has been pressed and released. For example, when the button is pressed and released for the first time, the LED will blink once; and when the button is pressed and released the second time, the LED will blink twice, etc. The button will be pressed once and release once each time. The LED shows a count (accumulated number of times Button was pressed).

You are asked to design an ohmic contact to p-type silicon using one of the metals listed in the table below. (a) Which metal should you use? Explain. (b) What is the maximum NA you could use? Explain.

Metal Ag Al Au Cr Ti W

?M (eV) 4.5 4.2 5.1 4.5 4.33 5.2

Describe the types of instructions supported by the ATmega8 microcontroller.

Using the parity bit, port b is to flash in a pattern of Odd Numbered LEDs On and Even Numbered LEDS Off for 1 second, and then Odd Numbered LEDs Off and Even Numbered LEDS On for 1 second. This pattern will repeat indefinitely. Please provide the both the assembly code for MPLAB and a flow chart. Note - consider delay calculations and port B initialization have already been completed.
