The complete flow, hands-on
Digital: RTL to GDSII. Analog: specification to GDSII. Every stage on open-source tools you keep using after the internship, with exposure to the commercial tools industry uses.
Choose your track: Digital VLSI or Analog & Mixed-Signal.
A hands-on internship for B.Tech students. Learn the complete chip-design flow on open-source EDA tools (with exposure to the commercial tools industry uses), build a capstone design of your own, and take it to a tape-out-ready layout — with the option to fabricate it on GF180MCU or UMC65 through the Vidyutt Academic Chip Shuttle (VACS).
Most VLSI courses stop at simulation or an FPGA demo. Industry hires engineers who have closed timing, matched a layout, fixed DRC violations and signed off a real design. This internship takes you through every stage of the chip-design flow on a single design of your own — and ends with a tape-out-ready layout you can send to the fab.
Digital: RTL to GDSII. Analog: specification to GDSII. Every stage on open-source tools you keep using after the internship, with exposure to the commercial tools industry uses.
Take your capstone design to silicon through the Vidyutt Academic Chip Shuttle (VACS) on GF180MCU or UMC65, and receive packaged chips for testing. Tape-out is optional and charged per tile.
Capstone themes in AI/ML hardware, neuromorphic computing, power management, sensor interfaces, cryptography and hardware security.
Weekly design reviews and signoff reviews with engineers who run the VACS tape-out flow.
Graduate with a GDSII of your own design, simulation and signoff reports, your design files on Git and, if you fabricate, a VACS tape-out record — evidence that recruiters and graduate schools can verify.
Both tracks run for six months, follow the same weekly rhythm, include the same mentorship and certification, and end in a tape-out-ready design. You choose your track on the application form.

The programme fee includes a validated open-source EDA environment and PDK. Every stage runs on open-source tools, with exposure to the commercial tools listed.
The Vidyutt Academic Chip Shuttle (VACS) is Vidyutt's Design-to-Silicon programme. Designs that pass technical review are combined on a multi-project wafer, fabricated, packaged and returned for testing. Every intern — digital or analog — finishes with a tape-out-ready design; sending it to the fab is optional and is charged separately from the programme fee.
| Technology node | Tile size | Tape-out cost per tile |
|---|---|---|
| GF180MCU | 300 µm × 300 µm | ₹35,000 |
| UMC65 | 200 µm × 200 µm | ₹35,000 |
The tape-out cost is borne by the intern (or shared by the project team) and is not part of the ₹50,000 programme fee. It covers signoff clearance, fabrication and packaging through VACS. Larger designs occupy multiple adjacent tiles, charged per tile.
Fabrication and packaging continue after the internship ends. Interns are notified when packaged chips arrive and are invited to join post-silicon testing and bring-up.
VACS tape-out (fabrication and packaging) — optional, ₹35,000 per tile: 300 µm × 300 µm on GF180MCU or 200 µm × 200 µm on UMC65. See the Tape-out section.
