Can a small silicon chip make a difference in a superpower vs. a 'wanna-be' superpower nation?
Yes, it is.
A tiny semiconductor chip can completely shift the balance of power between who needs it and who provides it.
This is why stepping up in semiconductor designing is crucial for a country like India, which is cementing its position as a new superpower on the global stage.
VIHAAN, India’s very first domestic broadband networking system-on-chip, could make that difference for the nation in the future.
The chip is especially designed for Wi-Fi routers, broadband equipment, and optical fiber access networks, which are vastly used in homes, shops, offices, malls, airports, hospitals, etc.
Designing a semiconductor chip is much more challenging than it seems, because a tiny mistake can become a blunder and cause months of delay along with billions of rupees spent on redesigning and re-fabrication efforts.
VIHAAN successfully overcame these challenges and is considered to be a unique and rare achievement in the semiconductor sector.
The Startup behind the VIHAAN!
VIHAAN is a 28-nanometre broadband networking System-on-Chip (SOC) developed by Aheesa Digital Innovations, a Chennai-based fabless semiconductor start-up.
This start-up has raised approximately INR 40 crore from the Tamil Nadu Emerging Sector Seed Fund and private investors and has also signed an investment MoU with the Tamil Nadu government.
VIHAAN is especially built around the native VEGA processor core, a series of high-performance microprocessors developed by the C-DAC (Centre for Development of Advanced Computing) under the RISC-V architecture.
This brings computing, broadband access and system control at its core together on a single silicon chip. The project is supported by the ‘India Semiconductor Mission’ and the Design Linked Incentive (DLI) scheme.
VIHAAN – Strengthening Base of Viksit Bharat!
In Sanskrit ‘Vihaan’ means dawn or morning which symbolizes a new start, and the beginning of a better future.
The silicon chip was taped out on 26 January 2026, and achieved its first-pass silicon success on 15 August 2026, i.e., Independence Day. The significance of these two dates further enhance the relevance of VIHAAN.
The importance of VIHAAN in 3 points:
First, VIHAAN achieved first-pass silicon success. It means this Indian-designed silicon chip performed as desired with no need of a single redesign or re-fabrication cycle.
Second, the design of this chip presents the high quality of the original architecture, verification, testing, and engineering.
And the third is SOC (system-on-chip), which means this chip integrates various functions successfully that might have needed different components before.
Actually, new age SoCs efficiently combine a processor, memory interface, input-output system, and specialized hardware into one compact silicon piece.
Let’s Understand the Working of VIHAAN
High-speed internet data arrives through the fibre infrastructure. The networking chip processes that data and helps convert it into the connectivity required by Wi-Fi or a wired LAN connection.
VIHAAN is carefully designed to handle this high-speed broadband data processing while also incorporating security features at the hardware level. Because the modern networking equipment does not only move data but also protects the system, and the data move through it.
Aheesa Router Operating System (AROS) will run VIHAAN, allowing this chip to integrate with routers, modems, and access points.
Less Dependency, Strong Digital Impact!
VIHAAN has been designed specifically for optical fibre access networks, used by telecom operators to deliver last-mile connectivity to homes and offices.
As India expands fibre broadband, 5G networks and broadband-led digital services, the networking silicon inside routers and optical network terminals becomes crucial.
If the networking chips used in this infrastructure are entirely imported, dependence does not end with the purchase of the physical device.
Technology, supply chains and long-term access to crucial components rely on foreign dependence.
That is why the need for a domestically designed chip surges to provide India better control over establishing strong digital infrastructure.
The Ministry of Electronics and IT confirmed on 15 August that the chip will move towards production tape-out, targeted for 2027, predicting it will significantly mark India’s digital presence on the global stage.
More Focus on Future: Indian Startups
India currently imports most of the chips used across its telecom and technology infrastructure. At the same time, the country has sharply increased public investment in semiconductor development through initiatives such as the ‘Semicon India Programme’ and the ‘Make in India’ initiative.
The vision is not just to assemble electronic products in India but to develop the intellectual property, processor architectures and chip designs that empower the brand image of those products.
In these efforts, the DLI programme is continuously supporting Indian start-ups working on semiconductor design across a range of applications, including satellite communications, drones, defence systems, automotive electronics, IoT devices and smart metres.
The Use of RISC-V Architecture
An Instruction Set Architecture, or ISA, is essentially the vocabulary of commands that a processor understands. It forms the interface between software and hardware.
For decades, some of the dominant processor architectures have been licensed. Companies designing processors around such architectures may have to pay royalties and remain dependent on the organizations controlling those technologies.
RISC-V has lifted this theory by offering an effective model. It’s an open-standard, royalty-free instruction set architecture (ISA), allowing organizations to design processors based on it with no need of a proprietary license.
VIHAAN uses the locally established VEGA processor, developed by C-DAC under the Digital India RISC-V (DIR-V) program. Alongside VEGA, the SHAKTI family developed by IIT Madras represents another major native processor initiative.
One Step Is Not Enough!
It's true that India’s semiconductor ambitions will not be achieved through a single breakthrough. It will require years of research, design, fabrication, testing, investment and the development of specialised talent.
With the growth of 5G, fibre broadband and broadband-led services, the demand for networking equipment is rising. Government efforts to encourage the use of Indian chips in networking equipment and routers could further create opportunities for domestic semiconductor start-ups.
Over the last decade, India has started reducing its dependency on foreign hardware and technology. But expecting an amazing result is too soon for now. VIHAAN is the first important step in the semiconductor sector, and this journey will be continued to place India among the few superpowers of the semiconductor world.
