## Synthesis on Xilinx FPGAs using Vivado

- Install Vivado (I'm using the free 2019.1 webpack edition).

- Setup Vivado paths:

```
source /opt/Xilinx/Vivado/2019.1/settings64.sh
```

- Install FuseSoC:

```
pip3 install --user -U fusesoc
```

- Create a working directory and point FuseSoC at microwatt:

```
mkdir microwatt-fusesoc
cd microwatt-fusesoc
fusesoc library add microwatt /path/to/microwatt/
```

- Build using FuseSoC. For hello world (Replace nexys_video with your FPGA board):

```
fusesoc run --target=nexys_video microwatt --memory_size=8192 --ram_init_file=/path/to/microwatt/fpga/hello_world.hex
```

- To build micropython (currently requires 1MB of BRAM eg an Artix-7 A200):

```
fusesoc run --target=nexys_video microwatt
```
