design and simulation tool.
To learn how to realize a digital design with descrete
components (IC’s, LED’s, switches, and resistors).

All designs and simulations
done in pre-lab must be printed and brought to lab. All
simulations should be annotated (using Quartus) to
highlight key points in the simulation. All Quartus
schematic printouts throughout the semester should
include your name, printed using Quartus and using a

It is much easier to debug a circuit from paper
then from a laptop screen.
You should be familiar with the operation of the Quartus
software, the breadboard functions, and basic logic design
prior to arriving at the laboratory.

Do all that is described in the pre-lab below, but use a
simpler equation, e.g. W = /A*B.
Using only AND gates with
