  Mojo V3 Bin Not Found
Posted by: jsanchez1996 - 03-25-2019, 11:21 PM - Forum: General Questions - Replies (1)

I keep getting a bin not found error when I build a project. It works with a simple project. I have looked at the old forum but they have not resolved the problem.

  How to add "Block Design" created in Vivado
Posted by: Rory - 03-24-2019, 02:55 PM - Forum: General Questions - Replies (3)

I want to add a customized block memory module to my Alchitry Labs project (I'm using an Alchitry Au with Vivado tools).

When I used to use the Mojo IDE and Xilinx ISE tools, I could just open the Xilinix "Core Generator", from the "Tools" menu within Mojo IDE. Then, once I had finished generating the core, it would show up as a component in Mojo IDE.

Now, Vivado doesn't have "Core generator" it has "Block Designs" that you can add, but I don't know how to add one to my Alchitry Labs Project.

I can open the Vivado project that Alchitry Labs creates, and from there, I can generate block designs, but I can't add these to Alchitry Labs, and the next time I hit "Build Project", Alchitry Labs just deletes and re-generates the Vivado project entirely.

Am I supposed to create a separate Vivado project, generate blocks, and import them? I suspect this is not how to do it, but I can't even do this, because I think there is a bug in Alchitry Labs that doesn't let me import. Whenever I try to import a file, it pops up with an error saying that a project must be open to import a file, even when a project IS open. (I am using Windows 10, Alchitry Labs 1.0.4, see screenshot).

Any help with how to add blocks generated from Vivado would be greatly appreciated. 


  Generic .acf or .xdc files for Au
Posted by: prebys - 03-22-2019, 04:32 PM - Forum: General Questions - Replies (2)

I just got an Au and Io to evaluate for use in a class at UC Davis.  I'm using the Alchitry program + Vivado. Managed to get the example job to compile and load (although most of the documentation still seems based on Mojo+ISE)

My question is are there any generic .acf and/or .xdc files for the Au or both, or is there at least better documentation than the schematics?   Ideally it would be nice to have an .acf file with *all* the connections commented out, then I could just uncomment the ones I need (like the Arty-7).  Mapping 24 LEDs and 24 DIP switches through two different schematics is kind of a pain.

  Clock Signals
Posted by: iggyglass - 03-21-2019, 04:51 PM - Forum: General Questions - Replies (14)

Hey, so while I was working on a project, I noticed that if I wanted to use an external input as the clock signal of a dff:

.clk(exampleInput), .rst(rst) {
  dff example;
it fails to compile and gives me the bin file not found error. 

I was wondering if there was any way to do this, or if this is a bug, or what.


  Mojo Max Milliamps

I'm working on a project that is pulling about 217 Milliamps thru the Mojo,  does anyone know the max per pin and the total for all pins in milliamps


  HDMI or video out shield for Alchitry Au

Hello, im really in the need of a HDMI or digital video output shield for my main fpga board, Im thinking to buy the Alchitry Au but dont know if you're going to release a shield like that.

  Uploading to Mojo crashes Alchitry Labs
Posted by: mc_deltat - 03-16-2019, 09:58 AM - Forum: General Questions - Replies (1)

Whenever I try to upload a project to my Mojo board, Alchitry Labs crashes instantly. No popup or error message or anything, it just closes.
Log file is attached.

  VS Code Integration
Posted by: r0ck3t - 03-13-2019, 01:39 AM - Forum: General Questions - Replies (3)

Is VS Code integration something that is being looked into in terms of supporting an IDE? It already has a bunch of great features, and platforms such as PlatformIO have made great use of it for something that is cross platform and runs great. This might free up some time from IDE support to specific features which would be great!

If this is not something that is/will be considered, I would be interested in implementing something similar since that is what I always use, and I am slow to adopt new IDEs.

  Onboard SRAM support
Posted by: r0ck3t - 03-13-2019, 01:36 AM - Forum: General Questions - Replies (4)

Is there a projected time frame for when on board SRAM is going to be supported? I have no problem writing support, but I would like to know I am not re-implementing something that is almost done, or already done by the board supporters!

  Simulation extensions
Posted by: r0ck3t - 03-13-2019, 01:35 AM - Forum: General Questions - Replies (1)

Currently the only way that I can think of to utilize simulations, for Lucid or Verilog, is to either, import the transpiled (or native) Verilog code into Vivado, then write my test bench there for simulation purposes. This is sorta clunky, but the simulations are very useful for more complex designs. 

Is there any future plans to implement some sort of simulation process into Alchitry Labs, or is this going to be the normal process?
