Vizsla

Language support for Verilog and SystemVerilog powered by the Vizsla language server.

This extension bundles the vizsla language server for the target platform and contributes syntax highlighting, language configuration, diagnostics, navigation, completion, semantic tokens, formatting, and code actions for Verilog and SystemVerilog projects.

Language Server Status

The status bar shows the Vizsla language server state: starting, ready, stopped, or error. Click the status item to open the Vizsla output channel.

The command palette also provides:

• Vizsla: Show Language Server Output
• Vizsla: Restart Language Server
• Vizsla: Show Server Version

When server launch settings change, the extension prompts you to restart the language server so the new command, arguments, working directory, or trace setting can take effect.

Configuration

The extension launches the bundled server by default. Advanced users can override the server command with vizsla.server.command and pass additional arguments with vizsla.server.args or vizsla.server.additionalArgs.

Most language server behavior can be configured from VS Code Settings under Vizsla, including diagnostics, file watching, formatting, inlay hints, code lenses, semantic tokens, and signature help.
