register generator suite
Hi, I need a genuine suggestion here. So, I have built a CLI tool that generates SystemVerilog RTL, UVM RAL, C headers, IP-XACT and Documentation from a single JSON register spec -- — with built-in lint and diff. I know already many similar tools exist but my tool has several features which you can't find in open source tool.
**What it does:**
- Takes a register spec (YAML, JSON, IP-XACT, SystemRDL, or Excel)
- Generates 6 outputs in one command: SystemVerilog RTL · UVM RAL · C Header · Markdown Docs · IP-XACT 2014 · SystemRDL 2.0
- **Lint/DRC**: 12 ASIC-focused rules to catch bugs before tape-out (address alignment, field overlaps, reserved gaps, etc.)
- **Diff & Impact**: Compares two spec versions and tells you exactly which RTL, UVM, C headers, and tests are affected — breaking vs non-breaking classified
- **SoC Merge**: Merge 50+ IP blocks into a unified, conflict-free top-level memory map
- **100% offline** — standalone binary, no Node.js, no cloud, air-gap ready
**CI/CD friendly**: lint and diff both return exit code 1 on violations, so you can gate PRs on spec quality.
Community Edition is free (2 registers per block to evaluate). 30-day Pro trial available with no credit card.
