Looking for FPGA board

I'm looking for an FPGA board for P2 development but I'm having problems finding them for purchase (and fitting my budget).
The Prop123 is out of my budget (dang!) and the DE0-nano does not have CORDIC.
I need a board that can support at least:
-one Cog
-64K RAM & the 16K ROM
-8 Smart pins
-CORDIC
Everything else is a bonus :-)
I'm looking at Terasic's page and the DE10-nano (110k LEs) and the DE0-CV (49K LEs) look good and are affordable.
But are they supported !?! Is there an image for them?
Alternatively, the BeMicro CV might work (25k LEs) but I can't find it anywhere to buy.
Can it fit the CORDIC unit?

Looks like DE2-115 is the smallest supported one that can fit cordic. (which is the toughest requirement, once you have cordic, everything else is ample..)
DE2-115 seems to ue

Notice the DE10-Nano price is well under the chip price !
DE0-CV is more $ and only 49k LE, so the DE10-Nano looks viable, but right now there is no compiled image for that.
@cgracey Any chance of a DE10-Nano compile??

Interesting question, but nothing on the current list has spare room to meet the other requirements, and add a cordic.
20k LE's or about 8k ALM'S.

It's inexpensive and can accommodate a decent portion of the P2.
Jason
It's 'reasonable', but would only be known if Chip decides to add a build for the DE10-NANO 5CSEBA6U23I7N
PortA only with 32K Hub and 8 cogs.
ALM usage jumps from 18% to 22%
Based on Chip's comment that the Cordic uses ~8K ALM's that's about 20% of the available ALM's.
A P2 build will come down finding a good balance of cogs and smartpins.
