SRAM or Flash based? Hardcores? Devkits and CAD tools? Education and training resources? Let's break it down.

Lattice Ice40 because FOSS workflow.
Wyatt Taylor
ICE40s are such shit, code than works well with the synthesizer doesn't always compile with the bundled simulator, there's little to no IP, not even an async FIFO, and it's only in verilog
You can really feel that Lattice bought SiliconBlue a couple of years ago and never bothered to properly integrated the ICE40s into their lineup

>generally
SRAM-based for run-time reconfigurable setups and frequently reprogrammed setups (development). Flash-based for fast startup and rugged deployment setups.
Bentley Jenkins
>Which FPGA's do you guys use and why?
OFC Xilinx.
bigger portfolio of products,
vivado rocks.
there are a shitload of libraries out there
Cuckltera is Kill.
Robert Parker
What's a good devkit and toolchain for an FPGA RISC-V processor development?
Asher Baker
cant go wrong with an altera
Brody Reyes
vhdl a shit
verilog strong
Tyler Carter
Verilog is cool for slapdash experiments that are disposable or otherwise have low liability. Some people think it's easier to learn but I learned VHDL first so I that's not part of my experience.
Jeremiah Anderson
It might be interesting to design a soft microprocessor core that implements the RISC-V ISA with an architecture that is specifically optimized for an FPGA implementation. There are a couple projects like:
github.com
github.com
But I haven't evaluated them in any way and I don't know how well they compare to something like the MicroBlaze.
Jason Jenkins
I have no idea what I could use an FPGA card but judging by the name I assume that it would have a lot of different uses. I already know that they're commonly used for hashing.
Do you guys reccomend any books or a website that goes into detail what FPGAs are used for ? Are there any foss FPGAs.
Blake Lopez
got myself a MAX 2 because it was cheap and I wanted something to get into VHDL
no periferals, but I have enough trigger, LEDs and even a 4x 7 segment display.
hopefully when it gets here I'll have something ready to start testing

You would probably need to understand basic electricity, electronics, and digital logic systems.

Can you post a link?
Hudson Edwards
I understand electricity but have little understanding of how a computer works so I'll look into it, thanks.
Sebastian Butler
That link to TPB needs a Tor Browser.
Dylan Watson
I got it covered, thx.

just got this to start learning FPGAs, because it's FOSS
Angel Brooks
What did you get?
Grayson Brown
I'd like to see PCIe FPGAs so we can have 1:1 hardware exactly like the original for emulators.
Jacob Anderson
I'm not sure what you mean. There are plenty of FPGA's with PCIe interfaces in addition to a variety of other high-speed SERDES interfaces.
Dominic Anderson
my bad, i'm a retard.
Liam Miller
Well, yes that is nice. But I'd like to see that particular use case more often. As far as I know, someone has only made a FPGA based SNES clone called Analogue and it seems to be 100% as the original hardware is.
Aiden Smith
Super cool. I haven't seen this before. Gonna check it out in detail. Thanks!
Leo Thompson
Vivado is pain incarnate
Matthew Long
Will FPGA prices ever reach $20-50, one is able to get used i5 CPUs at this price range
Wyatt Russell
Xavier Diaz
I have a Xilinx Basys3 laying around somewhere. Used it for a couple of university courses and found Vivado to be extremely unpleasant, even if VHDL wasn't that bad. Any suggestions for using the Basys3 or some other board without having to use Vivado?
Brayden Cox
I mean as in the entire development system/board, not just the chip
Nicholas Hughes
I doubt you'll get that, at least for Xilinx you need the platform cable which is $25 by itself (on AliExpress).
Nathaniel Torres
Synthesis software is painfully expensive. I've primarily used Synopsys. Microsemi offered a free Synopsys license and a free ModelSim license a few years ago but they've stopped recently...
Luke Martin
dude, I have no clue what I'll get at this point.
I wanted to start somewhere and for how little it costs I wouldn't care if I accidentally burn it down.
I'll try starting with an i2c bus to gpio.
should be small enough for the max 2, right?
ordered 2 breakout boards + usb blaster from aliexpress
just picked the cheapest sellers with some rep at least
already had a powerbrick, but you need one too probably
Ethan Lee

You can't get anything over 7k LUTs for that price
Elijah Ross
You can get a 33,000 logic element Artix-7 for $30 - $40 but you'll need to bring your own board.
Tyler Cook
DARPA is trying to fund open hardware in an attempt to simulate the success of FOSS. It seems like the hardware industry is behind the times a bit with potentially expensive proprietary toolchains and zero IP sharing. On the other front the RISC-V is only going to get better.
Nanofabs when?
Kevin Moore
Nice reference. Thanks!

At least then you'd be useful.
