One issue, the power up surge is 0.5A on the core VCC! That's a LOT!
This design would have 8 chips in a system, drawing 4 amps on power
up. That's pretty insane. Not sure this could be met, so may be a
show stopper.

don't surge simultaneously. That's a usual thing with power
electronics, motors, etc.

I am looking for an FPGA to use in my next board design. Efinix has some parts, although they are in very limited packaging. Everything is fairly find pitch BGA style, 0.4, 0.5 or 0.65 mm pitch.not a watered down web edition, it supports all of our FPGAs."
I've not worked with BGAs of that pitch. Otherwise their parts are interesting.

Then, there's the issue of not being able to get a working copy of the software until you buy an eval kit. That's very counter productive for many, since the software is something that needs to be checked out early in the process.
"We do not have a free version of the Efinity software. However, when you buy any of our development kits, you also get a software license and one year of upgrades. After the first year you can request a free maintenance renewal. The version you get is

That SW policy is unusual these days, and pretty short-sighted IMO.

who it was! Doh!That SW policy is unusual these days, and pretty short-sighted IMO.I agree. It is especially short-sighted when the development boards are hard to get. The Efinix web site recommends the Xyloni at $35, and provides a link to Digikey where they are $75 and not in stock.
My memory is often short. A trick that can be used to incorporate an ADC into an FPGA is to use an LVDS input as a comparator to support a sigma-delta converter. Most FPGA vendors don't really support this, but I saw one who did... I just can't recall
