Your Next‑Level EDA eXperience

NEX is a powerful, extensible automation framework that bridges the gap between hardware engineers and the increasingly complex EDA tooling landscape. Built on top of a proprietary multi-agent system framework, NEX is an intelligent control layer that sits between you and your operating system, seamlessly orchestrating workflows to accelerate digital design and verification.

Unlocking Real Electronic Design Automation

Modern hardware development means juggling simulators, synthesis engines, linters, verification environments, and build systems, often across different vendors and platforms. NEX brings these tools together behind a single, cohesive command-line interface.

Built with automation at its core, NEX takes on the repetitive and error‑prone work. From regression triage and documentation of legacy IP to large‑scale RTL refactoring, NEX handles the heavy lifting so you can stay focused on architecture, correctness, and performance.

Multiple Modes of Operation

NEX adapts to the way you work, offering different complementary interaction models:

  1. Co‑Pilot Mode

    • Interactive collaboration: Work side‑by‑side with NEX to explore ideas, investigate issues, and make progress in real time.
    • Intent‑driven tooling: Express goals and actions in natural language while NEX translates them into precise EDA and system commands.
    • Context‑aware reasoning & planning: Reason about design behavior, failures, and next steps using live context from waveforms, logs, and project state.

  2. Agent Mode

    • Autonomous workflow execution: Delegate complex, multi‑step tasks to NEX, from planning through execution and validation.
    • Self‑healing automation: When a build or simulation fails, NEX analyzes the results, adapts the workflow, and retries without manual intervention.

  3. Headless Mode

    • Scheduled, context‑aware work: Run regressions, synthesis, analysis, or reporting automatically on a schedule or trigger, with intelligent notifications on completion.
    • Background productivity: Continuously handle long‑running or routine tasks so you can stay focused on higher‑level design and decision‑making.

An Extendible Ecosystem

NEX is built to be vendor-agnostic and highly extensible. It does not replace your tools; it amplifies them.

  • Universal EDA Integration: Seamlessly integrates with Commercial Grade tools (Synopsys, Cadence, Mentor/Siemens, Xilinx, Intel) and Open Source stacks (Verilator, Icarus Verilog, Yosys).
  • Non-EDA Utility: NEX connects to your broader engineering environment, managing Git repositories, Python scripts, Makefiles, and CI/CD pipelines.
  • OS Integration: acting as a native extension of your Operating System, NEX can manipulate files, execute shell commands, and navigate directories with full awareness of your codebase and local environment.

Use it with Gemini 3 Pro or BYOA

NEX includes built‑in access to Gemini 3 Pro, already bundled with the standard pricing. You can start using NEX immediately without configuring external credentials or managing separate API subscriptions.

For teams with specific requirements, NEX also supports Bring Your Own API (BYOA). You can connect your own API key and select from major LLM providers, allowing you to tailor the underlying model to your performance, cost, privacy, or compliance needs.

This flexibility lets you choose between a fully managed experience or a customized AI backend—without changing how you interact with NEX or how your workflows are defined.

Enterprise‑Ready by Design

NEX is designed with enterprise security and data ownership as first‑class principles. By default, NEX operates entirely within the local machine or network environment where it is deployed and does not log, store, or transmit project data beyond that boundary.

For enterprise deployments, this means NEX can be configured to run with private models hosted inside your own infrastructure or secure network. Source code, design artifacts, logs, and execution context remain fully under your control and are never exposed to external services unless explicitly configured.

This architecture enables teams to adopt NEX in security-sensitive environments while meeting internal policies, compliance requirements, and data‑sovereignty constraints.

Try NEX Yourself

NEX is actively evolving, with new capabilities, integrations, and workflows landing regularly. The best way to experience what NEX can do is to try it yourself: a free tier is available for everyone, so you can explore the platform, run real workflows, and see how NEX fits into your design process before committing further.
