Lab 1-1: 4-Bit Mux and all NAND/NOR Mux

Module by: Chris Stevenson, Joseph Cavallaro. E-mail the authors

Summary: Briefly describes the tasks for Lab 1.1 of Rice University's ELEC 220 course.

Lab 1-1

4-Bit Mux

For the first part of Lab 1 you will first design a 4-bit mux, similar to the 2-bit mux covered in the tutorial on Quartus projects found here. An already started Quartus project complete with I/O pins and pin assignments for the DE0 board can be found on OWL Space. This will provide a helpful starting point and ensure a common board setup, making it easier for the labbies to check your circuits’ functionality. Download the .zip file and extract it to a temporary working directory on the C: drive, making sure to move it over to your U: drive before you leave the lab.

NAND or NOR only Mux

Create a new version of your original 4-bit mux using only NAND or only NOR gates. A useful tutorial for NAND/NOR conversion can be found here. Do not use inverters (NOT gate) or gates with inverted inputs in your design.

My Favorites (?)

'My Favorites' is a special kind of lens which you can use to bookmark modules and collections. 'My Favorites' can only be seen by you, and collections saved in 'My Favorites' can remember the last module you were on. You need an account to use 'My Favorites'.

Definition of a lens


A lens is a custom view of the content in the repository. You can think of it as a fancy kind of list that will let you see content through the eyes of organizations and people you trust.

What is in a lens?

Lens makers point to materials (modules and collections), creating a guide that includes their own comments and descriptive tags about the content.

Who can create a lens?

Any individual member, a community, or a respected organization.

What are tags? tag icon

Tags are descriptors added by lens makers to help label content, attaching a vocabulary that is meaningful in the context of the lens.
