Introducing the Mojo IDE

When developing for FPGAs we commonly would have three separate programs open. One program to write the code in, one to build the project, and one to load it onto our board. This is just a bit ridiculous. In following our goal of making FPGAs as accessible as possible, we are now developing the Mojo IDE.

It's my pleasure to announce our current release of the IDE, version 0.0.3 Pre-Alpha. As the name may give away, this is a very early build. It is, however, what we believe to be usable for basic projects. 

The lateste update adds real-time syntax error checking. It will underline syntax errors in red and give a tooltip to help sort out what caused the error when you hover over the error.


Sometimes, keeping your code looking nice can be a lot of tedious work. With the Mojo IDE, just press ctrl+shift+f and all your code will be automatically formatted. Right now this only includes indenting.

One-Click Building

The Mojo IDE integrates with Xilinx's PlanAhead tool to build your project without leaving the IDE. This does mean that you will still need to install ISE. Check out the Installing ISE tutorial for more info.

With ISE installed you will need to tell the Mojo IDE where it can find the PlanAhead program. To do this simply go to Settings->PlanAhead Location and browse for the file.

On Windows this is typically something like


On Linux this is typically


Once that is set you can simply click the hammer icon to build your project.

After you click the icon, you can view the results in the bottom section of the window.

If your project builds successfully you can then move onto the next step.

One-Click Loading

The Mojo IDE has the Mojo Loader code built right into it. This means that once you plug in the Mojo and select the serial port it's connected to (Settings->Serial Port) you will be able to click the arrow icon to load your project onto the Mojo. 

To get the Mojo to work, you need to follow the setup steps found in the Mojo Loader tutorial. The driver is included with the Mojo IDE download so you can just point Windows to the IDE's folder. 

The Mojo IDE knows where to look for the .bin file generated from the build process. That means you can just click the arrow and watch it load!

The Mojo IDE is being developed on Ubuntu 13.04. This pre-alpha has been tested to work on Windows, but there are a few minor graphics issues.
