2-bit Adder to 4-bit Adder in Verilog | Structural Modeling + Testbench + Simulation
2-bit Adder to 4-bit Adder in Verilog | Structural Modeling + Testbench + Simulation
Welcome to Chip Logic Studio (CLS) 🚀
In this video, we dive deep into Verilog HDL design by building a 4-bit Adder using a 2-bit Adder through structural (hierarchical) modeling. This is a must-learn concept for anyone preparing for VLSI, RTL Design, or FPGA development.
We start by designing a 2-bit adder module, then reuse it to construct a 4-bit adder, demonstrating how real-world digital systems are built using modular design principles. Finally, we verify the design using a testbench and simulation waveform, ensuring correctness.
