Laboratory Exercise 1 Switches, Lights, and Multiplexers
The purpose of this exercise is to learn how to connect simpleinput and output devices to an FPGA chip and implement a circuitthat uses these devices.
We will use the switches SW9?0 on the DE0 board as inputs to thecircuit. We will use light emitting diodes (LEDs) and 7-segmentdisplays as output devices.
Part I
The DE0 board provides 10 toggle switches, called SW9?0, thatcan be used as inputs to a circuit, and 10 green lights, calledLEDG9?0, that can be used to display output values. Figure 1 showsa simple Verilog module that uses these switches and shows theirstates
