PIB TrackerTaped out on Republic Day, working silicon by Independence Day
A Chennai fabless startup backed by the Design Linked Incentive scheme achieved first-pass silicon success with VIHAAN, a fibre broadband networking chip — the concrete version of the semiconductor ambition announced from the Red Fort.
What happened
- Aheesa Digital Innovations achieved first-pass silicon success with VIHAAN.
- VIHAAN is a networking System-on-Chip built for fibre broadband.
- It was taped out on Republic Day and returned working silicon on Independence Day.
- Production tape-out is targeted for 2027.
- DLI-backed companies have raised over $100 million and achieved 35 tape-outs.
For Prelims
- DLI Scheme: the Design Linked Incentive supporting Indian startups designing chips for strategic and commercial applications.
- Fabless: a company that designs chips but has them manufactured at a third-party foundry.
- First-pass silicon success: the fabricated chip works as designed without a re-spin — the practical test of design maturity.
- Tape-out: committing a finished design to fabrication; production tape-out is the commercial-volume step, targeted 2027.
- SoC: a System-on-Chip integrating processor, memory and interfaces on one die.
- Value-chain economics: design contributes up to 50 per cent of value addition and 15–35 per cent of the bill of materials cost.
- DLI portfolio: satellite communications, drones, surveillance, defence and aerospace, automotive, IoT, LED drivers, AI systems, telecom and smart meters.
- Investor: the Tamil Nadu Infrastructure Fund Management Corporation among others.
For UPSC: The concrete counterpart to semiconductor rhetoric. Use it for the fabless model and design-led value capture, the Design Linked Incentive scheme, why design capability precedes fabrication, and state-level venture capital in deep tech.
What it is NOT: First-pass silicon is a design milestone, not commercial production — VIHAAN's production tape-out is targeted for 2027, and the chip was fabricated at a foundry, not in India.
For Mains
Syllabus: GS3.13 · GS3.12 · Linkage L2
Anchor
Working silicon on the first attempt is the only semiconductor claim that cannot be made in a speech.
Substantiation (data)
First-pass success on a fibre broadband SoC, production tape-out targeted for 2027, and DLI-backed firms cumulatively raising over $100 million across 35 tape-outs.
Exemplification
Design captures up to half the value addition in the semiconductor chain — which is why a fabless startup matters even without a domestic leading-edge fab.
Problematisation
The chip was designed here and fabricated elsewhere; without domestic foundry access, design success still leaves the supply chain's chokepoint abroad.
Way-forward
Link DLI graduates to the fabs under construction and to public procurement in telecom and defence so first customers exist domestically.
Position
Semiconductor sovereignty is built one working chip at a time, not one announcement at a time.
Deploys into: Frontier technology + indigenisation (GS3.13, GS3.12) · the fabless model and design-led value capture, the Design Linked Incentive scheme, and state-level venture capital in deep tech.
