description Verilog Overview

Verilog is a hardware description language employed to create electronic system models. It’s notably utilized in designing Application-Specific Integrated Circuits (ASICs) and Field Programmable Gate Arrays (FPGAs). The language facilitates digital logic modeling for verification and simulation purposes. Verilog is commonly used by engineers, researchers, and students involved in VLSI design and FPGA development requiring a strong foundation in hardware architecture.

help Verilog FAQ

What is Verilog used for in hardware design?

Verilog is a hardware description language used to model digital logic for ASICs and FPGAs. Engineers write modules, signals, always blocks, and testbenches to describe and verify circuits.

How is Verilog different from a programming language like C?

Verilog describes hardware that can operate in parallel, while C usually describes sequential instructions for a processor. A Verilog assignment can represent wires, flip-flops, or combinational logic depending on how the code is written.

What is the difference between Verilog and SystemVerilog?

SystemVerilog extends Verilog with stronger typing, interfaces, assertions, classes, and verification features. Verilog was standardized as IEEE 1364, while SystemVerilog is standardized under IEEE 1800.

What tools can compile or simulate Verilog?

Open-source tools include Icarus Verilog and Verilator. FPGA vendor flows such as Xilinx Vivado and Intel Quartus also accept synthesizable Verilog for real hardware builds.
