Zuspec Backend HDLSim ===================== The Zuspec HDLSim backend enables co-simulation of Zuspec testbench descriptions with existing HDL designs (SystemVerilog/Verilog). It bridges Python-based Zuspec test environments with hardware simulators, allowing you to drive HDL designs from Python tests while executing critical paths in hardware simulation. The backend integrates with `DV Flow Manager (DFM) `_ to provide automated, declarative workflows for generating, building, and running HDL testbenches. .. toctree:: :maxdepth: 2 :caption: Contents: overview architecture quickstart components dfm_integration api_reference examples
