  1. 01

    Disconnected tools, slower progress.

    Engineers juggle multiple tools, manually write testbenches, run simulations, and switch contexts; which slows down development and increases errors.

Verification confidence

From spec to verified RTL, in one guided path.

RTLBridge connects specification, generation, verification, and target-aware delivery in one engineering workflow; so you can go from idea to silicon faster.

  1. 01

    Describe the spec

    Write in plain language, add optional specs and datasheets.

  2. 02

    Generate RTL + testbench

    Per-role models create Verilog or VHDL and a self-checking testbench.

  3. 03

    Verify & synthesize

    Run simulation, check coverage, and generate reports for your target.

Choose the right engine for each stage.

Different tasks need different models. RTLBridge lets you pick the best engine for planning, generation, and verification; optimized for cost, speed, or rigor.

  • Verilog & VHDL output

    High-quality, synthesizable RTL and testbenches.

  • FPGA & ASIC targets

    Target-aware flows for Xilinx, Intel, Lattice and more.

  • Evidence-driven iteration

From prompt to verified RTL; not just another code answer

General AI assistants can draft HDL. RTLBridge is built for the complete single-module hardware workflow: clarify the design, generate synthesizable RTL, run verification and synthesis, then refine the result using real tool feedback.

RTLBridge vs. general AI assistants

The difference is not access to an LLM. It is the hardware-specific workflow wrapped around it, from pre-RTL planning to verified, synthesis-informed iteration.

CapabilityRTLBridgeGeneral AI assistants
Pre-RTL planningClarifies module structure and requirements before codingDepends on prompt detail and manual follow-up
Synthesis-ready HDLDesigned to produce synthesizable Verilog or VHDLMay mix synthesizable RTL with abstract or unsupported constructs
EDA tool feedbackParses simulation and synthesis output directlyUsually requires engineers to copy tool logs back into chat
Verification loopCreates tests, runs them, and iterates on failuresCan suggest tests, but execution is normally manual
Resource estimatesUses synthesis-driven allocation and reportsEstimates remain ungrounded without a synthesis tool
HDL knowledge groundingGrounded in 500k+ vetted HDL sourcesBroad coding knowledge without dedicated HDL retrieval by default
Vendor-specific IPCan use device context and supported vendor IP, including Xilinx IP coresIP selection and instantiation need manual validation
Iterative refinementPatches RTL using code context and tool resultsSelf-correction is not grounded in executed hardware tools by default
Coding conventionsApplies the user's HDL style and conventionsRequires conventions to be restated and checked
VS Code workflowDedicated extension to build, debug and optimize RTL from the editorSome offer IDE extensions, but not the complete RTL toolchain loop

“General AI assistants” means broad chat and coding products used in their standard workflow. Capabilities may vary by plan, extension, and custom integration.

Bring a module specification. Leave with evidence.

Frequently asked questions

Quick answers about what the platform does, the HDL knowledge it expects, supported targets, and how usage is priced.

01

What does RTLBridge do?

RTLBridge is an AI-assisted RTL development platform for Verilog, SystemVerilog, and VHDL. It helps hardware engineers plan, generate, verify, debug, and optimize RTL designs, including testbench generation, simulation, waveform analysis, and synthesis workflows.

  • Verilog or VHDL RTL
  • Self-checking testbench
  • Simulation and coverage
  • Target synthesis report
02

Do I need to know Verilog, SystemVerilog, or VHDL?

No. You can describe your module requirements, interfaces, timing, reset behavior, and functionality in plain language. RTLBridge can generate the RTL and verification assets for you. Experienced HDL engineers can also inspect, edit, and refine the generated code directly.

03

Which FPGA and ASIC targets does RTLBridge support?

RTLBridge supports Xilinx, Intel, and Lattice FPGA targets, along with generic ASIC synthesis workflows. It can assist with RTL generation, verification, debugging, and optimization across supported hardware-development targets.

04

How does RTLBridge pricing work?

RTLBridge offers a Free plan with $4 of one-time usage credit, plus Pro, Max, and Team plans with monthly usage credit. AI usage depends on the models, project context, and tools required for each task, and additional usage credits can be purchased at any time.

05

Does RTLBridge have a VS Code extension?

Yes. The RTLBridge VS Code extension lets hardware engineers use AI-assisted RTL workflows without leaving their editor. You can work with existing repositories, generate and verify HDL, debug designs with waveform analysis, and optimize RTL directly from your development environment.
