Field-programmable gate arrays FPGAs are a very different to a regular microcontroller board. With a microcontroller you have control over is the software, the code that runs on the chip, but with an FPGA you start with a blank slate and design the circuit rather than write the code that runs on it. There is no processor to run software, at least not until you design it.

If you are interested in learning more about digital logic design, for sure you have to take a look at this new development board created by 1BitSquared called the iCEBreaker FPGA. Pre-wired, breakaway Pmod module — Input and output user accessible and usable in your own hardware design — Five LEDs in a star pattern — Three push buttons.

Our boards are taking a European vacation on the way to Australia. Hey did you get some valid timing constraints setup? So I think it often doesn't meet timing without this file being present and correct. I've been using Synplify in Linux and while yes I do see warnings they mainly appeared to be forward declaration types etc and I did get it to map okay.

Funny you mentioned LSE as being better as I had compiler issues with LSE but that was with a different codebase which probably still included some System Verilog bits and pieces that upset things, I might have to retry with the newer P1V code that I'm currently using that Magnus had cleaned up for Xilinx use.

Are you sure that the board needs a resistor mod for RTS? A while back I had asked Valentin to add it and his updated schematic shows it already connected via a 10k resistor to P89B pin as well as to the JTAG interface it does double duty for both purposes.

Hopefully this change actually made it into the final board rev so no-one should have to rework the board, at least that was my intent in requesting it originally. In some experiments I found that in my case the clock switching logic worked best for meeting timing if you only switch to 80MHz from a lower speed bootup clock eg. Clocks seem best driven directly from PLL outputs not via the original P1V clock divider circuit which has problems with timing.

Maybe having valid timing constraints could fix that, not sure As you say reusing flash after the FPGA switches to user mode should be possible to replace the i2c PROM with a custom booter which is doable - we already did this ourselves for MAX10 internal flash use too.

Lattice config documentation has more details there. I was just reading about that bit yesterday Cheers, Roger. Ariba Posts: 2, Thank's Roger for the many infos. It's hard to find in that part of the schematic especially if you have no clue that it could exist So we don't need to make any hardware modification - that's really great.

Thank's for bringig that to Valentin. I've not done serious timing analysis. I just looked at the max. I first used the internal oscillator with some dividers for all clocks and got higher values than with PLL. The rcfast clock is somewhat critical for a seamless download from PropTool. I can only download reliable, if the clock is around But I think we can use the internal oscillator for this clock if it simplifies the PLL usage for the other clocks.

Getting started with the Lattice iCE40 FPGA: Demo Boards, Programming w/ Radiant & iCEcube2 (Part 3)

I've tried to use the DCSC block for glitchless clock switching, but always got errors for unknown parameter names. The description in the appnote seems not to match the IP definition in Diamond. Maybe you can say me how the SEL input is called now. Normally Synplify is the better synthesis tool more standard but in this case it produces no working bitfile.These are in a 48 pad QFP package with 0.

I'm glad to hear it's finally available to us minions. Oh that looks like a cool little device. There is probably scope for creating a carrier board which gives access to all the IO but deals with any power and clocking in a breadboard friendly format maybe with a microUSB for connecting to the PC for programming. Hmmm, I can see an additional project coming up.

P1V - with Lattice ECP5 FPGAs?

The board has some electrical issues, so check the last link. It doesn't have a built-in programmer. Edit: it still seems to be in stock at gnarlygrey. I just looked at the other thread you linked to and then saw the schematic linked by shabaz for the board. I'd have not bothered even looking at the PCB based on the schematic design alone. It looks like a dogs dinner and almost no thought was put into it other than wiring up to every pin. Such a poor design for something which should have been really quick and easy to do right for anybody with even basic hardware design experience.

So I wonder if there is any desire for a well designed board for this part in a similar form factor to that UPduino? Or any suggestions for a preferred form factor, feature requests, etc? I'm probably going to start putting something together for a test board as it's not going to take long and I can probably get the boards done on a panel with some other things I am planning to get PCB's made for. Obviously a learning experience for him. I would be interested in one or two to start with if the price is good.

There are lots of boards from lots of vendors and none has hit the critical mass to be "the one" like Raspberry Pi. DIP form factor with 0. Don't populate the headers, since users may want to do something custom with them.

FTDI programmer, e. These are nice chips and software is easy, but unfortunately they are rather expensive It could be depopulated for a low-cost version that's programmable through an optional header. I think Lattice has an HX8K board that has jumpers for this. The important thing is to keep it really cheap, which is very hard to do in small quantities. Kickstarter is a good way to get the initial volume up and to gauge level of interest.

I think it is possible the price-point is low because it could be reusing old components, maybe. There was some comment on the other thread that the serial flash had strings in it from some other product:.

Print Search. I've spent a few days comparing a verilog design j1a cpu under IceCube2 and Radiant. They changed the names and parameter's formats with all primitives in Radiant, thus you have to migrate an existing design from the IceCube2 or IceStorm to the Radiant first.

Code: [Select]. Then you run the Reveal Analyzer. It is something similar to the ChipScope Xilinx.

The following users thanked this post: MasterTech.If you can master the FPGA, you can create hardware devices that not only morph and change based on your current needs, but can power through repetitive tasks at phenomenal rates.

The only problem is, working with FPGAs can be a bit intimidating for newbies. If everything goes according to plan, the wait might soon be over. Certainly a no-frills presentation. As the video after the break shows, you can even get away with using a sufficiently powerful smartphone to do some FPGA hacking on the go.

Essentially the heavy-lifting is done remotely: all of the synthesis is performed in their cloud backend, with the final bitstream delivered to the user for installation through WebUSB.

The more critical Hackaday reader will likely be concerned about lock-in. What happens if you buy one of these development boards without a license for the service, or worse, what happens if WebFPGA goes belly-up down the road? To that end, [Ryan] makes it clear that their hardware is completely compatible with existing offline FPGA development tools such as the open source IceStorm.

Yeah, it requires a different mindset apart from sequential thinking. The iteration loop of trial and error s much longer, so you want to design up front as much as you can and make sure things would work by doing a lot of simulation with the needed testbench. Debugging is hard as there are no visibility into internal circuit.

One would hope they let you select any given version they have ever hosted and log said version information in the projects so opening an old project will by default build it with the exact toolchain and configuration you used before lest you get non-reproducable builds. Of course the board is compatible with an offline toolchain, nobody builds a new toolchain just for their cloud service.

Back then there were not PCs at the edge; the decentralization and democratization of computing was nothing short of revolutionary. It is sad to see how willing people are to throw all those gains away and cramming all manner of applications through ghastly browser-based interfaces to boot.

I would not use this. FOSS on my local machine is the good stuff. Cloud computing has a cost too. It needs a lot more resources than your typical web hosting server.

So they use the cloud loophole to keep everything proprietary a instead. The minuscule demographic interested in FPGAs is minuscule for a reason.

Both the proprietary and FOSS toolchains are painfully cumbersome for people who want to tinker around with FPGAs for the first time — either students or hobbyists. There is an argument against embedded hobbyists picking up an FPGA board. In the end, this is a product that scales with the user.

Do that. No clue what an FPGA is but have a curious and willing mind? Black Beauty is a good one. There are lot of embedded computer these days. To take control from you is exactly the point of the cloud, it makes more money, if you are dependent. The very operating system that was meant to give you fine-grained control and freedom.

Only for those rolling in their victimhood. This is what we need more of.

Sign in to your account. This is my first Kicad symbol PR, please let me know of any errors I've committed. I decided to break this symbol up into multiple parts, I hope that's OK.

All committers have signed the CLA. So I believe the remaining violations are just because I made a multi-part symbol.

If there's a way to resolve these violations, or if I should just make one big giant symbol, please let me know. You can get ride of this by making the symbol bigger. Second travis error relates to that normally the power supply should be on top and bottom of the symbol, with some exceptions, like for power supply modules.

So there are four units in this symbol. The first unit is centered or was, possiblybut because the refdes and description must be in the same place on every unit, I couldn't center the other units without moving them far away from the refdes. Happy to resolve this however you like, just not sure what is the right thing to do.

Unit support seems Somewhat half baked, but it's very useful for FPGAs. I made some cleanup changes based on feedback I've gotten on my other symbol PRs. I'd still like some pointers on how to properly handle multi-unit symbols, though. There's shouldn't be any intrinsic issues caused by multi-unit symbols. The centering thing is probably our algorithm.

I'll let Misca finish reviewing this. Misca Is there anything that needs to be done to get this symbol merged?

Let's see how shakes out and then I'll jump in and do another review so we can get this merged. We need another FPGA symbol now and I'd rather have a decision before trying to contribute that, too. Yes, power and ground pins should be top and bottom. If you'd update this symbol, split or not, and post a screenshot we can move forward with review. Sorry for the delay, everyone - I made this change six weeks ago but apparently didn't update the screenshots.

You can see the current state below:. I'm inclined to merge this when it's ready, but your voice is important here. The way we currently have them, you can see at a glance what the IO voltage of a pin will be.

I'd be OK with moving them to the top of their current units. On the QFN48, it's an open drain output which is low during configuration and then floating weakly pulled up afterwards. I agree the datasheet is confusing.

Page 32 specifically lists the iCE40 UltraPlus as one of the parts using it, so I'm pretty sure it's page There's no guidance on a footprint from Lattice, and as far as I can tell, no guidance from the KLC on thermal pad size relative to the pad on the part.

I can switch to the 5.
