Formal and equivalence checking
Synthesis, static timing, place and route
Sign-off: DRC, LVS and GDSII export

Stalnix Super Intelligence

A conversational AI assistant we are building on large language models, with one difference: it is designed to verify and fact-check every answer before it reaches you, and to show the sources and the checks alongside.

Chat, reasoning, writing and code
Every answer verified before it is delivered
Fact-check report with each response
Sources shown alongside
Says so when evidence is thin or sources disagree

RTL to GDSII, in one platform.

We are building one environment for the whole chip design flow: simulate, verify, synthesise, time, place and route, sign off and tape out. Every step will share the same design database, so nothing is exported, converted or lost between tools.

Features

Every stage of the flow.

The capabilities we are developing, front end to back end, with verification and sign-off built in rather than bolted on. All are work in progress.

SimulationVerilog, SystemVerilog, VHDL, SystemC and mixed-language designs in one simulator. Four-state logic with strength resolution, timing checks and SDF back-annotation, gate-level simulation, and analog/mixed-signal co-simulation with real-number models.

VerificationNative UVM with constrained-random stimulus, sequences, scoreboards and register models. SystemVerilog assertions, functional and code coverage with closure dashboards, lint, CDC and RDC analysis, and a growing library of protocol VIPs including AMBA, USB, PCIe, Ethernet and I2C/SPI.

Formal and equivalenceProperty checking with bounded model checking and k-induction, assume-guarantee decomposition, and logic equivalence checking between RTL and gate-level netlists. Formal engines are under active development.

SynthesisLogic optimisation, technology mapping with drive-strength selection, timing-driven retiming, FSM encoding and arithmetic optimisation. Design-for-test with scan insertion, ATPG and built-in self-test. Liberty-based cell libraries.

Static timing analysisPath-based STA with multi-mode multi-corner analysis, on-chip variation derating, clock reconvergence pessimism removal, crosstalk-aware delay and parasitic back-annotation from SPEF. Slack histograms, path browsers and bottleneck reports.

Physical designFloorplanning, placement and legalisation, clock tree synthesis with tree and mesh options, global and detailed routing with congestion awareness, parasitic extraction, and static and switching power analysis.

Sign-off and tapeoutDesign rule checking and layout-versus-schematic with violation browsers, GDSII and OASIS export, open process design kits (Sky130, GF180) and a hand-off path to established open-source back-end flows. A tapeout readiness checklist tracks sign-off.

FPGAThe same RTL and testbenches targeted at FPGA for prototyping and emulation, with synthesis and bitstream generation in the flow.

Workspace

Everything in the browser.

We are developing a web-based IDE with the full flow behind it: no installs, no licence servers, no switching between tools. Open a project and start simulating.

Editor and debuggerLanguage-aware editing, breakpoints, signal watch, design hierarchy and a time-travel debugger that steps backwards through a simulation
Waveform viewerSignals, transactions and UVM activity in one timeline, with protocol decode
DashboardsCoverage, timing, power, DRC and LVS results as live panels, not log files
RegressionsSuite management with pass/fail matrices and failure triage
AI co-pilotAn assistant inside the IDE that explains failures, drafts testbenches and answers questions about your design
TeamsShared projects, code review with inline comments, and an IP catalogue to reuse blocks across designs

Status

Where we are.

Stalnix EDA is in research and development. We are developing and verifying each stage of the flow on open process design kits, hardening the engines and expanding language coverage ahead of an initial release.

Now

Research

Developing the engines for simulation, synthesis, timing and physical design, and verifying them against open-source RTL and reference designs.

We plan an initial version for early design teams, followed by general availability.

Answers you can check.

A conversational AI assistant that will do everything you expect from today's chatbots, and one thing they don't: we are building it to verify and fact-check its own answers before you see them, and to show you how.

What makes it different

Verified, not just generated.

Large language models are fluent, but they can state things that are wrong with complete confidence. Stalnix Super Intelligence is being designed to treat every answer as a claim to be checked.

Verification before deliveryEach answer will be broken into its claims and checked against trusted sources and independent reasoning before it is shown. Claims that cannot be verified will be marked, not hidden.

Fact-check reportEvery response will come with its verification details: which claims were checked, what supports them, and a confidence level for each, so you can see exactly what stands behind the answer.

Sources, shownCitations will be attached to the specific statements they support, with links you can follow, rather than a general list at the end.

Honest about uncertaintyWhen evidence is thin or sources disagree, the assistant will say so and show both sides instead of picking one and sounding sure.

Everything else you expect

A complete assistant, in the making.

Conversation and reasoningMulti-turn chat, step-by-step reasoning and long-context understanding of documents
Writing and researchDrafting, summarising, translation and research across the web and your own files
CodeWriting, explaining, reviewing and debugging code across common languages, with hardware languages included
Engineering depthBeing built by chip designers, with the depth to reason about hardware, specifications and verification as well as software

Status

Where we are.

Stalnix Super Intelligence is in research and development, with the verification layer as the core of the work. We plan an initial version for early users, followed by general availability.

Stalnix Accelerator · In development

Compute for the AI era.

A family of GPUs we are developing for AI and graphics, from large enterprise data centres to a single workstation. The architecture is designed to scale across the range, so models trained in the data centre can run unchanged at the edge.

The range

Three classes, one architecture.

Data centreRack-scale systems designed to connect many GPUs into one accelerator for training and serving large language models, for enterprise and cloud deployments.

WorkstationA single-card GPU for engineers, researchers and creators: local AI inference, fine-tuning and professional graphics on the desk.

ConsumerGraphics and on-device AI for gaming and personal use, with the same cores as the professional parts.

SoftwareOpen compiler and runtime support, planned so that existing AI frameworks can run without rewriting code.

Roadmap

Every generation, faster.

Our research targets a step up in performance with each generation: more tensor throughput, more memory bandwidth and better efficiency per watt, so the same power budget does more work every time.

Generation 1

Foundation

Architecture definition, simulation and verification of the compute, memory and interconnect blocks, using Stalnix EDA end to end.

Higher clock and core counts, faster memory and multi-GPU interconnect, with each generation planned to raise performance and efficiency over the last.

Status

Where we are.

The Accelerator is in research and development. Details of the first silicon will be shared as the design matures.

Engineering

Built by chip designers.

Our products are built by engineers with deep experience in real silicon, from specification to tapeout. That is why we can build an AI chip, the tools to design it, and the intelligence that runs on it.

Automotive and IoT SoCsSafety-critical and low-power system-on-chip design and verification

About

Engineering silicon, end to end.

Stalnix Semiconductor was founded in 2026 with one long-term goal: a complete, independent stack for designing silicon, from the tools engineers use to the intelligence that works alongside them. Headquartered in Chennai, built for the world.
