Python, through libraries such as cocotb, can be used to interface at the signal level to Verilog and VHDL hardware description language (HDL) simulations, and can offer a very productive alternative to the SystemVerilog/UVM testbench methodology. But, what if you have an existing SystemVerilog or UVM testbench and want to call a reference model implemented in Python? What if you want to write tests in Python and call tasks on an existing protocol verification IP (VIP) implemented in SystemVerilog? Existing approaches often involve complexities of generating C/C++ wrapper code and getting it properly compiled and linked with the simulator. Often, the wrapper-generation process must be performed by the end user, making it more difficult to produce reusable libraries that are easily used by others. In addition, differences between simulator implementations of multithreading and Python’s co-routine implementation impose significant obstacles to implementing time-consuming behavior that spans HDL and Python code. The PyHDL-IF family of Python libraries provides a (very-nearly) pure-Python interface that enables object-oriented cross-calling between Python and HDL environments. PyHDL-IF enables Python to be easily incorporated in SystemVerilog environments and enables cocotb environments to interact with the HDL environment via task calls.
