It offers a comprehensive development environment, including advanced synthesis, simulation, and debugging tools. Vivado’s user-friendly graphical user interface (GUI) makes it a top choice for both beginners and experienced designers.

ModelSim

ModelSim is a widely-used simulation tool that supports both Verilog and VHDL. It is renowned for its robust debugging and simulation capabilities, making it ideal for complex projects. ModelSim is a favorite among many engineers who need reliable and efficient simulation tools.

Quartus Prime

Intel Quartus Prime is another excellent tool for FPGA design that supports Verilog. It includes comprehensive synthesis, simulation, and programming tools, making it a versatile choice. Its design flow and easy-to-use GUI make it a popular option for FPGA developers.

Open-Source IDEs

Icarus Verilog

Icarus Verilog is a highly regarded open-source Verilog simulation and synthesis tool. While it may lack a full-fledged GUI, it can be easily integrated with text editors like Visual Studio Code (VS Code) or Sublime Text, making it an ideal choice for developers who prefer lightweight tools. Its modular design and compatibility with various environments make it a popular choice among open-source enthusiasts.

Verilator

Verilator is a high-performance Verilog simulator that converts Verilog code into C or SystemC for simulation. It is particularly useful for large designs and can be integrated into various development environments. Verilator is known for its speed and ability to generate efficient C code, which can significantly speed up your simulation process.

Eclipse with SystemVerilog Plugin

Eclipse with SystemVerilog Plugin is a flexible development environment that can be easily customized to support Verilog and SystemVerilog. Eclipse’s rich set of extensions and customizable features make it a versatile option for developers. Whether you prefer a GUI or a command-line interface, Eclipse can be tailored to meet your needs.

VS Code with Extensions

Visual Studio Code with Extensions provides a modern and customizable coding experience for Verilog. The VS Code platform, combined with various extensions, allows for efficient and intuitive development. This makes it an excellent choice for developers who value productivity and ease of use.

Alternative Open-Source IDEs

rochus-keller/VerilogCreator

rochus-keller/VerilogCreator is an open-source IDE based on Qt Creator. It supports Verilog 2005 syntax checking, coloring, and semantic code navigation/highlighting. With build configurations for Icarus Verilator, Yosys, and Tcl, this IDE is a great option for open-source flows like Project IceStorm and SymbiFlow.

Notably, the recent version of VerilogCreator supports Marker-Based Code Folding (MBCF), a feature known from Emacs and Vim. This powerful tool allows you to define arbitrary sections and collapse them for easier navigation. It can also support elements from SystemVerilog such as assert, assume, cover, and restrict, making it a highly configurable and flexible option.

Based on your specific workflows, preferences for GUI vs. command line, and the complexity of your projects, the best IDE for Verilog will vary. If you prioritize a versatile and customizable environment, Eclipse with SystemVerilog Plugin or Visual Studio Code with Verilog extensions might be the best choice. For those on a budget and looking for open-source options, Icarus Verilator or rochus-keller/VerilogCreator can be excellent alternatives. Ultimately, the most suitable IDE depends on your unique needs.
