An example Arty-A7 project using hdlmake

Hello HDLMake

Intro

This project is an evaluation of the hdlmake tool for use on the Arty-A7 development board from Digilent. The top module is a simple application that does the following things:

• Pulses a red LED from one of the RGB LEDs
• Reads in characters at 1,000,000 baud from the USB to UART converter
• Displays the lower 4 bits from the last character read on the UART
• Prints the last character read as fast as possible on the USB to UART converter

Synthesizing the bitstream

1. Ensure Vivado is installed. I used 2019.2.
2. Prepare a Python 3.7 virtual env. Older versions of Python 3 might work, but Python 3.7 is what I use. On my machine I did the following:

bash> python -m virtualenv --python=$(readlink -f $(which python3.7)) venv
bash> source venv/bin/activate
(venv) bash> pip install six hdlmake git+https://github.com/adwranovsky/buildingblocks.git

3. Generate the makefile.

(venv) bash> cd syn
(venv) bash> hdlmake

4. Synthesize the bitstream.

(venv) bash> make
