Welcome to SymbiFlow examples!

This guide explains how to get started with SymbiFlow and build example designs from the SymbiFlow Examples GitHub repository. It currently focuses on the following FPGA families:

• Artix-7 from Xilinx,

• EOS S3 from QuickLogic.

Follow this guide to:

• install SymbiFlow and all of its dependencies,

• build and upload example designs onto the devboard of your choice.

• compile and run your own designs using the Symbiflow toolchain.

• customize the Makefile for your own designs.

• gain valuable information about Understanding Toolchain Commands in Symbiflow
