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..)

    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.
  • Thanks JMG ! This is an awesome overview!

    @cgracey Any chance of a DE10-Nano compile??

  • Wonder how many LE's the Cordic is

    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.
  • I just got a DE NANO 10, been reading and playing but not with Prop2. Would also love to see a small build for it also.

  • How many other people would do testing on the P2 if there was a DE10-nano image?
    It's inexpensive and can accommodate a decent portion of the P2.

    With CORDIC installed, is it reasonable to expect the DE10-nano could still host four COGs?

    It's 'reasonable', but would only be known if Chip decides to add a build for the DE10-NANO 5CSEBA6U23I7N
  • FYI Here's the stats for a standard P1V build for the DE10_Nano for reference.
    PortA only with 32K Hub and 8 cogs.

  • And here's a build for a 512k hub P1V with PortB included (64IO)
    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.

  • So it sounds as if the DE NANO 10 would make a minimal useable P2. Would not want to take Chips valuable time at this point of development but perhaps later esp after I re learn my way around Quartus again. Did build a P1 with additional memory years ago!
