Register Automation
LiveOne register spec, every output - RTL, UVM RAL, C headers, and documentation that never drift apart.
Why it exists
Registers live in a spreadsheet, the RTL lives in a repo, the firmware headers live in another, and the documentation lies about all three. Every mismatch is an integration bug waiting for bring-up to find it.
RegBit generates everything from a single register specification: synthesizable RTL, UVM register-abstraction-layer models for verification, C headers for firmware, and human-readable documentation - all guaranteed consistent because they share one source.
What it does
Generate clean, reviewable register-block RTL directly from the specification, with standard bus interfaces.
UVM RAL models come out of the same spec, so the testbench and the design can never disagree about a field.
C headers generated in lockstep - hardware and software teams read from the same truth.
Register documentation regenerates with every change instead of rotting in a wiki.
How it compares
Where this tool stands against the open-source path and the commercial incumbents - capability by capability.
| Capability | RegBit | Spreadsheets + homegrown scripts | Commercial register-management suites |
|---|---|---|---|
| Single source of truth | One spec, all outputs | Spreadsheet drift | Yes |
| RTL generation | Included | Custom scripts | Yes |
| UVM RAL generation | Included | Rare | Yes |
| C header generation | Included | Custom scripts | Yes |
| Cost model | Platform access | Free + maintenance burden | Enterprise licence |
| Deployment | Local-first via Escanor | Local | Licence server |
