Fabless · VLSI · Mixed-signal

We design chips. Foundries build them.

Thoshini is a fabless semiconductor company. We architect, design, and verify integrated circuits in Coimbatore, then tape out to global foundries. No fab. No factory. Just silicon, done right.

Indian engineering talent. Global semiconductor customers.

The design house
Architecture

From product idea to tape-out plan.

Spec, partitioning, node selection, IP strategy, and a build plan that respects budget, schedule, and silicon reality.

RTL & Verification

Verilog, SystemVerilog, UVM.

RTL design and constrained-random verification with UVM. Coverage-driven sign-off, not bug-hunting in silicon.

Learn more
End to end

Architecture to packaged part, one team.

Specification, RTL, verification, physical design, DFT, foundry tape-out, OSAT packaging, and silicon bring-up. No handoffs lost in translation.

See what we build
Physical design

Floorplan, place, route, sign-off.

Timing closure, power, IR drop, and DRC/LVS sign-off for mature nodes from 180nm down to 28nm.

Learn more
Bring-up

First silicon, first boot, first sale.

Post-silicon validation, characterisation, and reference boards so the customer can integrate on day one.

What we do

One design house. Every step covered.

We own the chip end to end, architecture through bring-up. A single team carries the part from spec to packaged silicon, with no handoffs lost between vendors.

Architecture & spec

Product spec, block partitioning, node and process selection, IP strategy.

RTL design

Verilog and SystemVerilog for digital and mixed-signal blocks.

Functional verification

UVM, constrained-random, coverage-driven. Verification you can sign off on.

Analog & mixed-signal

Analog layout, mixed-signal integration, and post-layout simulation.

Physical design

Floorplan, place-and-route, timing closure, IR drop, DRC/LVS sign-off.

DFT

Scan insertion, ATPG, BIST, and boundary scan for production test.

Tape-out & shuttle

GDSII sign-off, mask preparation, and shuttle or full-reticle tape-out coordination.

Packaging & test

OSAT package selection, test program development, and qualification.

Silicon bring-up

First-silicon validation, characterisation, and reference board development.

Inside the design house

Real silicon. Real engineers.

A look at the work — the screens where RTL gets written, the benches where first silicon gets characterised, and the boards that prove it all works.

Got a chip idea? Let's build it.

Send us a product spec, an architecture sketch, or just a description of what the silicon needs to do. We'll come back with a feasibility note and an honest plan.
