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).

Installation

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

Usage

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 .
