Installing the library

pysv is a pure Python library and can be installed via the following command:

pip install pysv

Environment setup

Although pysv is a Python package, in order to run Python code in SystemVerilog, we need a complete C++ tool-chain. Below are system environment requirements:

• cmake 3.4 or newer

• Any C++ compiler that supports C++11:

  • Clang/LLVM 3.3 or newer (for Apple Xcode’s clang, this is 5.0.0 or newer)

  • GCC 4.8 or newer

• Python 3.6 or newer

That being said, it should run smoothly in most systems since all it needs is a C++11 capable compiler. If your system’s default cmake is too old, you can try to use the one from PyPI:

pip install cmake

SystemVerilog simulators

pysv is designed to be simulator agonistic: it can work with virtually any simulator that supports DPI function calls. Since pysv generates C++ code, it naturally supports Verilator. Here is a list of simulators that pysv has been tested on:

• Cadence® Xcelium™

• Synopsys VCS®

• Mentor Questa®

• Vivado® Simulator

• Verilator
