Waveform Debug
LiveA waveform viewer that understands your design - protocol decoding and AI-assisted debug, at desktop speed.
Why it exists
Debug is where verification time actually goes, and the standard options are a dated free viewer or an enterprise debug seat. Raw signal traces make you decode protocols in your head, bit by bit.
WaveBit is a modern, desktop-native waveform viewer built in Rust for speed on large dumps - with six protocol decoders that turn raw signals into readable transactions, and AI assistance that helps you interrogate what you're seeing.
What it does
A Rust core and the Wellen waveform engine keep multi-gigabyte dumps scrolling smoothly.
Six protocol decoders render buses as transactions, not bit soup - read what the design did, not just what the wires held.
Ask questions of the trace and get oriented in unfamiliar signals faster; the waveform stays the ground truth.
Your simulation dumps never leave your machine.
How it compares
Where this tool stands against the open-source path and the commercial incumbents - capability by capability.
| Capability | WaveBit | GTKWave / Surfer | Enterprise debug platforms |
|---|---|---|---|
| Large-dump performance | Rust core, built for scale | Struggles at size (GTKWave) | Strong |
| Protocol decoding | 6 decoders built in | Limited / plugin-dependent | Yes |
| AI-assisted debug | Built in | None | Emerging, licence-gated |
| Modern UX | Native desktop app | Dated (GTKWave) / young (Surfer) | Workstation-class |
| Cost to start | Platform access | Free | Enterprise seat |
