SystemVerilog and Verilog Formatter for VSCode

Beautify SystemVerilog and Verilog code in VSCode through google/Verible

NEW: Now working in Windows, Ubuntu, CentOS and more!

WARNING! This extension will only work out of the box for the supported pre-built OSs detailed below. For other OSs you might need to build Verible yourself and have it in your PATH.

Installation

To install SystemVerilog and Verilog Formatter, search it in the Extensions tab inside VSCode, or install it from the Marketplace.

Alternatively, you can also clone this repository and build the sources yourself, then install it from VSIX.

OS Support

As of now, Verible binaries are released for a limited number of OSs and versions. If your OS or distro is not listed below, you can give it a try with the one that is most similar to yours, some users have been able to use it in different distros as well. Otherwise, you can build Verible for your OS and use that selecting build "none".

• CentOS-7.9.2009-Core-x86_64
• Ubuntu-16.04-xenial-x86_64
• Ubuntu-18.04-bionic-x86_64
• Ubuntu-20.04-focal-x86_64
• Ubuntu-22.04-jammy-x86_64
• win64

The following builds are provided from an archived version because they are not included in the latest official builds. These are provided to make this formatter compatible with as many systems as possible, but note that support might be limited.

• CentOS-6.10-Final-x86_64
• CentOS-8.2.2004-Core-x86_64
• Ubuntu-14.04-trusty-x86_64
• Ubuntu-19.10-eoan-x86_64

Select which binary you want to use by setting systemverilogFormatter.veribleBuild in the Settings dropdown or in your settings.json as:

{
  "systemverilogFormatter.veribleBuild": "Ubuntu-19.10-eoan-x86_64"
}

The beginning of the string is used to select the version, so Ubuntu-19, Ubuntu-19.10, Ubuntu-19.10-eoan... are all valid values that will select Ubuntu-19.10-eoan-x86_64. By default it will use win64 in Windows systems. In Linux systems it will try to find whether it's running CentOS or Ubuntu (which are the only pre-built ones for now), and otherwise default to Ubuntu.

You can use this extension with any OS not listed above but in that case you need to provide your own build of Verible and make it accessible in your PATH. Then select "none" in the veribleBuild dropdown in Settings, or add this to your settings.json:

{
  "systemverilogFormatter.veribleBuild": "none"
}

Commands

Native formatting:

This extension integrates with VSCode formatting, so you can use the built-in Format Document, format-on-save... and any linked functionality.

Format document

You can use the SystemVerilog Formatter - Format this file command from the command palette to apply formatting to the whole current document; or assign a Keyboard Shortcut to systemverilog-formatter-vscode.formatDocument

Format selection

You can select a portion of the file and use the SystemVerilog Formatter - Format selection command from the command palette to apply formatting to just that section of the document; or assign a Keyboard Shortcut to systemverilog-formatter-vscode.formatSelection

Configuration

The behavior of the formatter can be customized with additional command-line arguments. You can find a complete list of the supported arguments here.

Add the arguments that you desire to customize in systemverilogFormatter.commandLineArguments. By default no additional arguments are added and default values are used.

Example of custom values:

{
  "systemverilogFormatter.commandLineArguments": "--column_limit 80 --indentation_spaces 4"
}
