cocotb-vivado

A limited Python/cocotb interface to the Xilinx Vivado Simulator simulator. Based on cocotb-stub-sim.

The project is at a proof of concept stage

Only top-level ports are accessible (simulator limitation).
It supports the Timer trigger (simulator limitation).
Setting signal values is immediate, as one would use setimmediatevalue (simulator limitation).
Only Verilog at the top level is supported (to do).
Direct access to XSI interface

pip install cocotb-vivado==0.0.3 (for VIVADO <= 2022.2)
pip install cocotb-vivado (for VIVADO >= 2023.1)

See the tests folder for examples.

source ../Vivado/202X.X/settings64.sh
export LD_LIBRARY_PATH=$XILINX_VIVADO/lib/lnx64.o
pytest -s

Extra future: One does not need to recompile the project when running/changing tests .

We'd like to thank our employer, Dectris for supporting this work.
