SpinalTemplateMill

A simple SpinalHDL demo project based on SpinalTemplateSbt ported to the Mill build tool.

Setup

1. Ensure some reasonable version of Java is installed, e.g. OpenJDK. Works with 1.8.0, tested with 13.0.2.8 also. If you get an error about missing jni.h, also install the development package, e.g., java-*-openjdk-devel.

2. Install the Mill helper script according to the official documentation steps somewhere into your path, typically /usr/bin/mill, /usr/local/bin/mill, or in your home directory ~/bin/mill.

3. Ensure a recent version of Verilator is installed if you want to run simulations. Also install gtkwave for inspecting simulation waveforms.

4. Clone the repository and change into the project top-level directory.

$ git clone https://github.com/typingArtist/SpinalTemplateMill.git
$ cd SpinalTemplateMill

1. Choose target to run or build:

• With Verilator installed, run the simulation as the default target:

  ```sh
  $ mill simple.run
  ```
  

You can inspect the Verilog output afterwords in ./simWorkspace/MyTopLevel/rtl/MyTopLevel.v. Run gtkwave ./simWorkspace/MyTopLevel/test.vcd to inspect the waveforms.

• Or just generate Verilog output:

  ```sh
  $ mill simple.runMain mylib.MyTopLevelVerilog
  ```
  

The generated Verilog output is written to ./MyTopLevel.v.

• Or just generate VHDL output:

  ```sh
  $ mill simple.runMain mylib.myTopLevelVhdl
  ```
  

The generated VHDL output is written to ./MyTopLevel.vhd.
