DVICode: DV Intelligence for VS Code

Free, open-source SystemVerilog and UVM navigation for VS Code.

Follow definitions across packages and class hierarchies, see what a macro expands to, and explore your design and UVM testbench without starting a simulator. DVICode runs on your desktop, in WSL, or beside your sources on a Linux server over SSH. Currently in preview.

Features

• Errors as you type: undeclared names, unknown types, members and ports, missing includes and macros, syntax mistakes.
• Go anywhere: definitions, references, implementations and overrides, through macros, packages, class inheritance and port connections.
• Smart completion: members after ., package items after ::, macros after `, and complete module instantiations in one step.
• Hover documentation: signatures, doc comments and what a macro expands to.
• Design Hierarchy and UVM Verification Hierarchy views, worked out from the source.
• Macro expansion: see exactly what a `uvm_* macro turns into.
• Type and call hierarchies, outline, symbol search, rename, semantic highlighting.
• Quick fixes: "did you mean", "import package", "declare variable".
• Uses your existing file lists (-f files), or configures the project by itself.
• Works where your sources live: natively on Windows, Linux and macOS, in WSL, or on a Linux host over SSH, even for files that exist only on the server.
• Lightweight: a single engine of about 5 MB, installed for you. No telemetry.

Getting started

Open a folder with SystemVerilog sources; the engine runs on your computer. For files in WSL it runs in that WSL distribution; for files on a Linux server, run DVICode: Open Folder on the Server... and pick the SSH host (SSH key or agent sign-in). To control the compile order, add .dvicode/default.build in the simulator's argument-file syntax (-f, +incdir+, +define+, -uvm, ...); without it the project is configured automatically.
