Good find. So the rigor of the paper regarding fine details can be questioned. But then again, we can learn about various mid stream enterprises and companies that supply Chinese military ( at least their names and products offered).

The thing on semiconductors maybe dismissed. Never read of it anywhere, except that FPGAs have been hard nut to crack for China ( but one china started cracking nevertheless). Although there indeed is a lag in very high end semiconductors (CPU,GPU) but that has to do with broader fabrication lag which we all know.
These are supposed to be secrets?

Depends on the person, i guess. I have always wanted to know more about various enterprises in the midstream and upstream of Chinese MIC. It gives me a sense of scale and robustness. Very few countries have this broad and deep networks.

I think it is probably safe to say that IGBT is a "cracked nut" for China. But this report does not mention either CRRC's 株洲中车电气时代 or BYD.

How many military uses actually need FPGAs? I can see usefulness of FPGAs in weapon prototypes and during weapon development. But using FPGAs in large scale deployments in service seems excessive to me. Could the report mistakes FPGAs as DSPs or ASICs?

FPGA's are very important ( too important) for any military with serious MIC.

All the more evidence that China doesn't have FPGAs as a weakness. (If it was, it'd have been found and exploited to the hilt by now. No authorized sale happen to China's MIC from US anyway as its banned, sanctioned or stopped).

If you go to page 14-15, here is what it says.

以军用 IGBT 芯片为例,100%依赖进口; 以军用 FPGA 芯片为例,95%依赖进口。

"For military-grade IGBT, 100% reliance on import. For military-grade FPGA, 95% reliance on import."

Can someone please explain what is going on is this doc? I am not an expert in finance and do not have the political background clearance to know the exact level of PLA reliance on imported chips!

How are they being imported? If it was a weakness it would've already been exploited to the limit. But it hasn't.

IGBT isn't even a difficult technology. It is power semiconductor which has gigantic line widths like in micron range.

That's not true. There are companies in China that make FPGA.

ASIC is a better choice for large scale deployment. Not just the cost, but ASIC also runs cooler and many military applications are temperature sensitive.

It's something that I read years ago and something that I recollect quite well. That article you cited is good.

...a few semiconductor startups have dipped a toe into the FPGA pool.A few of the devices offered by these PRC FPGA vendors incorporate “high-speed” transceivers, but the maximum data rates offered are much lower than the transceiver speeds available in devices from US-based FPGA companies. Bigger and better FPGAs from these companies are sure to follow, as evidenced by the early information about the Seal 5000 family from Xi’an Intelligent Silicon Tech...
