How Machines Count to Nine

This lab manual details the construction and simulation of a BCD decade counter, a digital system designed to cycle through numerical values from zero to nine. The core hardware components involve the 74LS90 integrated circuit, which functions as the primary counter, and the 74LS47 decoder, which translates binary data into signals for a seven-segment display. Beyond physical implementation, the text emphasizes modern engineering techniques by requiring students to develop VHDL code and verify the circuit’s timing and logic via a digital simulator
