Actually the requirements have pretty much converged. We have actually done work for controls in nuclear, aerospace and now autonomous land vehicles. Designing for cars is actually the toughest since cost has to be low. Aerospace has some weight restrictions but SW reliability and system reliability...

One could very well make the opposite case, that the standards in auto industry are higher than in the aerospace industry. Think of the lowly Maruti 800. It has to last 10-20 years with minimal maintenance, with no fuel quality control, no sheltered storage and driven by mostly unqualified drivers !...

But I would focus on the TR modules using 3rd party GaN devices and the associated computing infrastructure first. I keep pushing for home grown systems first, home grown components can come later. That's a sensible idea. But on that topic, are Triquint & Cree marketing their GaN-based HEMTs in...

I heard it was a question of precision engineering to compact specs and reliability, plus then the materials issues and all sorts of stuff comes in. LCA I am told is a pain to work for, because of the size issue. Everything is small, light and has to be ultra reliable. Most suppliers give it a pass...

A western actuator guy was scathing about the denial to India. He said WIPRO and another bunch were making actuators locally anyhow so he didn't see what purpose the dont sell thing served. ISRO had a program running with HAL for the LCA actuators. Hopefully this year they'll enter trials. I am sti...

Marketing no, available yes for triquint . But defence would be the wrong focus, vehicle radars and mobile basecstaion PA s would probably drive usage in India. Defense would be a spin-off. Unfortunately I do not see much activity here. I am trying to setup a center for autonomous vehicles and have ...

I see. From time to time some US based firms have been advertising their RF and even components/devices to local industry, advertorials etc, but I always have had this perception that its 1 step ahead, 2 steps back. Many idiosyncratic decisions to deny us consultancy on LCA, actuators etc - which w...

Another GaN lab, in Trichy

IIT M has good faci!ities for wireless research, the correct system was conceived here. I think our labs
now work on LTE. So I am pretty sure they evaluate GaN power amps.

Thanks again. Completely agree about owning the designing and then doing import substitution! So GaN device availability is not seen as an issue? Somehow I had the mindset we'd have to rush to the west again for the same.. and sanctions would bite or some restriction or the other. So how has SITAR ...

Yes, not sure what the current state is. I can ask, but then I will get dragged into yet another project ! Prefer to maintain my focus on Shakti.

http://www.cense.iisc.ernet.in/pelectronics.html , GaN lab at iisc. They are also mlooking to set up a small fab.

I never back down in a technical or an intellectual debate ! Have a family clan history of 1000 + years of scholarship in vishitatdvaita, so I am fairly well prepared for any debate. Coming to GaN, the Sitar fab was active a while ago on gas but not sure now . SCL is looking at GaN and next gen Semi...

My open source work is done under a non profit called Macaque Labs. Drawing inspiration from the Bonnet Macaques at IIT. You can call me Madhusudan, which is my name but anyone who hangs around the Macaques would be honored to be equated to them ! Absolutely wonderful creatures who seem to be far mo...

Tough to mentor remotely. But both our and the UCB program is easy enough to follow and contribute online. For chip design, only two languages worth mentioning - Bluespec and Chisel. Do not even bother with Verilog, System Verilog or System C For OS type SW - Rust and of curse you have no choice but...

Not really, tough to guess arch from GDS , but access to die does open security risks but those can be mitigated. ------- Thanks for your reply sir. One question. How difficult/easy is it to reverse engineer the architectural level blocks from the layout level (GDS) design? ++. No fear of loss of IP...

question/s: * 64 bits I assume 32,64 and 128 bit (storage systems need 128 bit when you architect with unified memory and storage address space). We have our own secure microkernel OS. * What %age of Fab is within? That is a boat load!! Currently only proto in 180nm is with SCL. I think they may mov...

What is crucial is that all the design IP (especially the RS channel for Mil applications) originates and stays in India. Local manufacturing as I pointed out in another thread is happening at 180nm. Not exactly state of the art but more than enough for design validation and field deployment in non ...

On the subject of avionics, the building blocks for local avionics is well under way 1. Not sure if the group has been following the Indian processor development efforts, but we are making some progress. See my EE Times interview http://www.eetimes.com/document.asp?doc_id=1328790&page_number=2 A...

1. IIRC your program also has BARC's involvement right? Or is that a separate microprocessor program? I am sorry, I can comment only on the open part of our research. I prefer to not even mention who we work with in the strategic areas. But this program as I mentioned is a DIT program with CDAC bein...

Actually Processors, Motherboards and SoCs are one area where we do not have a problem and are pretty self-reliant. 1. DRDO already does its own custom ARM and PowerPC SoCs that have been deployed sucessfully. Granted the CPU cores are imported but most IP is available from Indian companies - PCIe, ...
