I found the part I had been interested in, the AGM AG6K SoC with a 250 MHz
ARM Cortex processor, 6,000 LE FPGA, 128 kB SRAM, 12 bit ADC, all in a 100
pin QFP package. Works for many of my apps although these days I'd prefer
an 88 pin QFN I think. Good density and still works with 6/6 mil design ru
les, but it has that thermal pad in the center while makes vias difficult u
nderneath the package, so maybe 100 pin QFP is better still unless you are
really constrained for space.
Still, I don't see a way to buy this part. So the Gowind parts have that b
ig advantage. It looks like you can actually buy them.

There parts seem to be compatible with other company's products...
AGM has independent intellectual property rights in software and circuits.
In terms of products, it is currently compatible with mainstream manufactur
ers and the software and hardware ecology is unchanged. The internal interf
ace of the chip is compatible with mainstream manufacturers, and the PCB bo
ard level can be directly replaced and compiled with AGM software. Import p
rogramming. 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.
I know in the past Altera has prevented the use of the bitstreams generated
with their tools, so I even if someone could legally make a bit stream com
patible chip, I don't know how they could program it without writing the to
ols separately. The web site does say to contact them about tools and prod
uct, so I guess they have their own tools and are not yet working through d
