VLSI lab and Assignment

The project involves VHDL design and simulation of digital circuits used in VLSI systems, focusing on:

• Multiplexers, demultiplexers
• Full adders, full subtractors
• Flip-flops (SR, JK)
• Binary to Gray Code Converter

These components are crucial in digital electronics, particularly in event counting (e.g., the counter for VLSI systems).

Why did you decide to make it?

• The purpose of this project is to explore digital logic design using VHDL, an essential tool in creating efficient and compact designs for VLSI systems.
• To understand the importance of modular design in digital systems and optimize for low power in VLSI.

How does it work?

• VHDL code was written for each component (multiplexer, adder, subtractor, flip-flop, etc.) and tested using testbenches.
• Simulation results (waveforms) validated the functionality of the components and ensured the designs matched the expected behavior as outlined by the truth tables.
• The VHDL-based digital counter was tested, and output values were displayed using a seven-segment display.
