Turnkey ASIC process

The Turnkey ASIC Development
Process: 8 Gated Stages

Every stage ends in a sign-off gate that you approve before we proceed. You always know where your chip is, what it has cost, and what happens next — a gated program you can put in front of your board.

Feasibility & specification

Wks 1–3

Your product requirements become a chip specification — PPA targets, process node, packaging and a unit-cost model. We tell you honestly if an FPGA beats an ASIC at your volumes.

Why turnkey ASIC

Why Choose Turnkey ASIC
Development? Risk Transfer.

The reason to buy turnkey isn't the price of engineering hours. It's that the three things that quietly kill chip programs stop being your problem.

Ours

Respin risk

Gated, coverage-driven verification exists to prevent it. When a respin traces to our design work, the contract says we correct it at our cost — agreed before we start, not argued afterwards.

Ours

Schedule risk

Fixed-price milestones tied to gates. Our team is already ramped — EDA licences, foundry accounts and silicon-proven IP in place — so month one is engineering, not recruitment.

Ours

Vendor-seam risk

No hand-off between a design house, a fab broker and a test house — the seams where programs quietly lose quarters. One team, one plan, one accountable party.

Your ASIC Design Partner —
A Team Already Ramped

While you'd spend 12–18 months recruiting a chip team, ours starts in two weeks — EDA flow, foundry access and silicon-proven IP already in place.

  • Full-stack, in-house. Architecture, RTL, UVM, RTL2GDSII, DFT and validation — no subcontractor roulette.
  • Silicon-proven IP library. Production-tested RTL, analog and verification IP that skips months of development.
  • Tier-1 EDA everywhere. Synopsys Fusion Compiler, Cadence Innovus, ZeBu & Palladium, Calibre signoff.
  • ISO 26262 discipline applied to every program — not only the automotive ones.

Turnkey ASIC FAQs

Turnkey ASIC Solutions
FAQs

NRE typically runs from a few hundred thousand dollars for a mature-node mixed-signal ASIC to several million for an advanced-node SoC — driven by node, die size, IP content and qualification level. Our free 21-day feasibility study quantifies NRE and unit cost at your target volumes, so you decide with real numbers instead of a range.

A typical program runs 12–18 months: 6–9 months to tape-out, 3–4 months of fabrication and packaging, then 3–5 months of validation and qualification. Mature nodes reusing proven IP land at the fast end; automotive qualification adds time at the far end.

As a rule of thumb, above roughly 50,000–100,000 lifetime units on mature nodes — and often earlier when power, size or BOM integration matter, since one ASIC frequently replaces an FPGA plus several discrete components. Your feasibility study includes a break-even model, and we'll say plainly if an FPGA is the better answer for you.

You do — completely. All RTL, GDSII, test programs and documentation created for your program are your property under the contract. Where our pre-existing silicon-proven IP saves you time, you receive a perpetual royalty-free licence for your product. Third-party design-database escrow is available.

Our gated, coverage-driven verification methodology exists to prevent exactly that, and the large majority of our designs work on first silicon. When a respin is needed, responsibility is defined in the contract up front: defects traceable to our design work are corrected at our cost. You never discover risk allocation after the fact.

We deliver designs across mature and advanced nodes through established tier-1 foundry relationships and their MPW shuttle programs, with qualified OSAT partners for packaging and test. Node selection is an engineering decision we make with you during feasibility — driven by your performance, power and unit-cost targets.

Yes — rescue and hand-off programs are regular work for us. We audit the existing design database, deliver a gap report with an honest completion estimate, then carry the design through tape-out, qualification and production under our design-to-production model.

A mutual NDA is signed before any technical exchange. Programs run in access-controlled project rooms with need-to-know data segregation, and your program is never staffed alongside a direct competitor's.
