Experimenting with FPGA open-source toolchains.
The FPGA that is developed on is the iCEstick from Lattice Semiconductor.
This expands on other FPGA open-source tools such as icestorm and iverilog among others.
A quick script is used to generate the directory structure for new modules, simply run perl create.pl <module> <project> to create a folder with all the necessary files.
If the project is the same as the module name (i.e. you're creating a small sub-module) the project field can be omitted.
> perl create.pl module project
