Simulator Integration

SystemVerilog (DPI)

Source

The PyHDL-IF SystemVerilog package must be compiled prior to compilation of code that uses PyHDL-IF artifacts. If you use a FuseSoC-based build system, simply place a dependency on fvutils::pyhdl-if.

If you directly specify sources:

  • Obtain the share directory by calling:

    % python3 -c 'import hdl_if; print(hdl_if.share())'
# OR
% python3 -m hdl_if share

  • Specify ${share}/dpi as an include directory

  • Specify ${share}/dpi/pyhdl_if.sv as a source file

DPI Shared Library

Two shared libraries must be specified as DPI libraries to the simulator:

  • PyHDL-IF entrypoint

  • Python

Obtain the paths to these libraries by running:

% python3 -c 'import hdl_if; print(" ".join(hdl_if.libs("dpi")))'
# OR
% python3 -m hdl_if libs --type dpi

Specify these as DPI libraries to your simulator using its preferred mechanism.
