Toolchain Setup notes

A quick guide on how to setup the open-source APIO tool-chain for the iCEbreaker FPGA board under Windows.

Installation and Build

First, install the apio toolchain:

> pip install -U apio
> apio install --all

With the board connected, the USB drivers can be installed. This will have to be redone if the board is connected to a different USB port.

> apio drivers --ftdi-enable

In the pop-up, find the board ('iCEBreaker (Interface 0)') and replace the driver with 'libusb' using the labeled button.

Once this is completed, reconnect the board.

To verify the verilog code:

> apio verify

To build:

> apio build

To verify, build, upload:

> apio upload

To do a timing analysis:

> apio time

To get more information about the build (including FPGA usage):

> apio build -v

To start the simulation (requires a testbench):

> apio sim

To initiate a new project in an directory:

> apio init --board iCEBreaker
