Now I think I am remembering the AG6K and AG10K from AGM, who's parts are a lso mostly discontinued.
Here is an interesting MCU/FPGA from their web site.

I believe when I dug around I found AGM was connected to another company in an unclear manner, maybe it was Gowin, can't remember. It may have been A nlogic, or maybe that's the 'A' in AGM... lol
Here is an excerpt from a two year old press release...
"AGM has independent intellectual property rights in software and circuits. In terms of products, it is currently compatible with mainstream manufactu rers and the software and hardware ecology is unchanged. The internal inter face of the chip is compatible with mainstream manufacturers, and the PCB b oard level can be directly replaced and compiled with AGM software. Import programming. AGM currently supplies devices that can be directly replaced: ? CPLD series for ALTERA MAX II series, including EPM240T100, EPM57
0T144, EPM570T100; ? Mini1K series 1K (QFN48), providing cost-sensi tive design solutions for LATTICE iCE series; ? low-end FPGA SoC Se ries for ALTERA Cyclone-IV EP4CE6, EP4CE10, EP4CE22; ? High-end FPG A SoC series BlueWind for the Xilinx Virtex series."
This seems to be saying they are legally supplying copies of other company' s chips including Lattice, Altera (Intel) and Xilinx. I also found a news article with an interesting leadin.

I didn't know any of this was banned or restricted.
