Introduction

The goal of this lab is gain familiarity with busses in Electric VLSI and design a ring oscillator as well as 8 bit AND OR NAND and NOR gates.

Methods

First a ring oscillator was designed using inverters from a pervious lab.







The following shows the designed 8-bit AND gate.







The following shows the designed 8-bit OR gate.







The following shows the designed 8-bit NAND gate.







The following shows the designed 8-bit NOR gate.







Results

Simulating the ring oscillator produced the following results.



Discussion

The ring oscillator produced expected results. All designed 8 bit gates passed all error checks.
