RTL Linting
LiveCatch RTL issues before they reach signoff - deep SystemVerilog linting in your editor and your CI.
Why it exists
RTL problems found at signoff cost days; the same problems found while typing cost seconds. Most teams either pay for a heavyweight static-signoff licence or run fragmented open-source checks with no editor integration and no consistent reporting.
LintBit is a modern RTL linter built on the pyslang SystemVerilog frontend - with an LSP server for live in-editor diagnostics, SARIF output for CI pipelines, and guided fixers that repair issues instead of just flagging them.
What it does
Full-fidelity parsing via the slang frontend - the same class of language accuracy the big static tools rely on, on every file you save.
A Language Server Protocol (LSP) implementation puts diagnostics inline in VS Code and any LSP-capable editor, while you type.
SARIF output drops straight into GitHub / GitLab code-scanning views, so lint results live where code review happens.
Guided auto-fixes repair common violations directly, turning lint from a report you triage into a step that cleans the code.
How it compares
Where this tool stands against the open-source path and the commercial incumbents - capability by capability.
| Capability | LintBit | Verilator / Verible | Commercial static-signoff lint |
|---|---|---|---|
| SystemVerilog language accuracy | Full-fidelity slang frontend | Good, with gaps in newer constructs | Full |
| In-editor diagnostics (LSP) | Built in | Partial (Verible LSP) | Rare / IDE-locked |
| CI integration | SARIF out of the box | Text output, custom glue | Proprietary reports |
| Auto-fix | Guided fixers | Limited (Verible format) | No |
| Platform context | One suite, shared design context | Standalone | Standalone tool silo |
| Deployment | Local-first via Escanor | Local | Licence server, per-seat |
