prunefl

prunefl is a utility that given a list of SystemVerilog files and a top module, returns the minimal list of files required for the top module to compile.

Building

Requirements

• git
• CMake 3.30+
• Python
• clang-tools (optional, for linting)

Steps

# configure will automatically be called
make -j$(nproc)

Nix

nix build -L

The binary will be in ./result/bin/prunefl.

Usage

$ ./build/prunefl -f test/mvp_model/mvp_model.f --top module_b --output-flags-to flags.f --output pruned.f

pruned.f will contain the pruned file list, but to propagate defines, libraries, include paths and such forward you may want to pass flags.f to the tool instead (which points to the pruned file list using a -C in a single compilation unit.)
