MicroNova Mercury 2 / SymbiFlow example project

This is a test project for the MicroNova Mercury 2 development board using the SymbiFlow open source toolchain instead of Xilinx Vivado.

Mercury 2 - Xilinx Artix-7 FPGA development board — MicroNova (product page)
Resources - Mercury 2 — MicroNova (schematics, pin constraint file, etc.)
MicroNova Mercury 2 FPGA Development Board - CNC Wiki (aggregated information)

I run these commands to generate a bitstream:

export INSTALL_DIR=~/apps/symbiflow
export FPGA_FAM="xc7"
export PATH="$INSTALL_DIR/$FPGA_FAM/install/bin:$PATH"
source "$INSTALL_DIR/$FPGA_FAM/conda/etc/profile.d/conda.sh"
conda activate $FPGA_FAM
make

And this command to flash the board:

./flash.sh

There are some customizations that may be needed for your system:

change the INSTALL_DIR variable in the build commands above to match your SymbiFlow location (in my case it's ~/apps/symbiflow)
change in ~/apps/mercury2_prog in flash.sh to reflect where you've placed the Mercury 2 Programmer Utility

This test project was based on symbiflow-examples, specifically the counter_test project.
