# fpga
Experimenting with FPGA open-source toolchains.
## Tools
The FPGA that is developed on is the [iCEstick](https://www.latticesemi.com/icestick) from Lattice Semiconductor.
This expands on other FPGA open-source tools such as [icestorm](http://www.clifford.at/icestorm/) and [iverilog](http://iverilog.icarus.com/) among others.
A quick script is used to generate the directory structure for new modules, simply run `perl create.pl ` 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
Creating module module files.
+- module/Makefile
+- module/module.sv
+- module/module_tb.sv
+- module/icestick.pcf
```
## Builds
adder : Simple adder module.
count : Binary counter.
dance : LED pattern display.
