Pulse: A New VHDL Simulator

Pulse is a new open source VHDL simulator written in C++ by Óscar Grimal, released under an MIT license. It provides a full toolchain including a compiler and a text-based user interface for waveform output, requiring only a C++20 compiler and CMake as dependencies. The project is still early-stage, supporting only basic IEEE packages and types, with default values not yet implemented. The roadmap includes generics, additional types, an improved simulation engine, and eventual mixed-language support with Verilog. Commenters note the included example project appears to contain non-standard or invalid VHDL, missing library imports and questionable type usage, suggesting it may currently suit educational use more than production synthesis workflows, unlike the more standards-strict GHDL.
