Just saw a potentially egregious claim saying that Chinese parallel processing standards (regarding RDPS/RSPs) are crap, and I quote "their FPGAs and ASICs domestically are consistently couple generations behind. And still a large part are imports that are not top notch. Not close to top Xilinx or Altera architectures."

I'm certainly not the most well-versed in this field but I do remember vaguely reading literature that makes me think that's absolutely not the case. I'd appreciate if someone can correct me or debunk this. @tphuang?
Where did you read this? Don’t tell me reddit. If we have to debunk every stupid claim on the internet then how do we find time to craft quality shitposts???

well, I'm not sure why that's posted here, since military grade FPGA and commercial grade are probably quite different.

Can we please not be stupid and post this kind of stuff in Semi thread in the future?

Like I'm honestly annoyed that you polluted a page of this thread with off topic nonsense.

That was said in the context of military use btw, so yeah. I'm aware that military aeronautics don't use SOTA stuff but my question remain(ed). I'll admit I probably should've clarified that I was looking for military applications though.

Jeez. Everyone starts somewhere. Be kind! Imagine if you inquire about aeroengines and I spat that in your face. Just because you're more knowledgeable in this aspect does not give you the room to act this unprofessionally. I'd like you to get off the pedestal, thanks.

"Off topic nonsense" is not an accurate description given that I was looking for information in terms of military grade FPGA. Again, I admit that I should've clarified but just because you misinterpreted my intentions does not make it "off topic nonsense." Cheers!

A quick word to @siegecrossbow: the burden of proof indeed wasn't on any of you, however did I insist that it was? No. I merely inquired (politely even, as I should). You can simply choose NOT to respond and I'm baffled that you even felt the need to say that considering that this a forum, which, involves people asking questions and others answering them. I'm throughly disappointed in all of you for not being able to treat this like rational adult human beings.

Okay the issue is that this is off topic. Since you are asking about FPGA, this should be in the semi thread.

If you want to ask a question about how FPGA is used in radars and which Chinese FPGA makers could possibly supply radars, then this is right thread. So please, if you are interested this, ask in that thread. We have threads for different topics and if you want to know where China's FPGA development is at, semi thread is a good place to start looking at. And then if you have questions, you can ask there.

No idea but I was willing to give them the benefit of doubt. After all electronics aren't what I'm most familiar with. They might've been right for all I know, that's why I asked.

Now that's a more appropriate response. Thank you.

My hostility wasn’t directed at you but the guy making baseless claims. Also, I don’t understand why you feel the need to get evidence from us to win internet arguments against such people. People will believe what they want and I don’t see the point in convincing them. You winning the argument will not make Chinese FPGA magically better, and you losing the argument will not make Chinese FPGA technologically backwards.

I'm certainly not well-versed in radar-related topics, but has this slide been posted before?

According to the slide, (GaN?)-on-Diamond heat-exchange/cooling technology has already been used on large, high-power radar systems and is in overall superior to DARPA's ICECool technology. The photo on the right consisted of the name of Harbin Institute of Technology.

Is this a screencap from biilibili? If so can you find the original link to the video? Probably some interesting morsels of information we can dig up.
