Pulse: A New Open-Source VHDL Simulator

A new open-source VHDL simulator named Pulse has been developed, aiming to offer an alternative to existing tools.

Developed in C++ by Óscar Grimal under an MIT license, Pulse is an ongoing project that includes a compiler and waveform output. The waveform output features a text-based user interface (TUI) for cross-platform compatibility.

Dependencies for Pulse are a C++20 capable compiler and CMake. Due to the complexity of VHDL, current support is limited to basic IEEE packages and types, with default values not yet implemented.

The project's roadmap indicates plans to add more VHDL features, including generics and additional types, along with an improved simulation engine. Mixed-language support with Verilog is also planned, but SystemVerilog support is not a priority.
