    GHDL

    GHDL

    VHDL 2008/93/87 simulator

    This directory contains the sources of GHDL, the open-source analyzer, compiler, simulator and (experimental) synthesizer for VHDL, a Hardware Description Language (HDL). GHDL is not an interpreter: it allows you to analyze and elaborate sources for generating machine code from your design. Native program execution is the only way for high-speed simulation. Full support for the 1987, 1993, 2002 versions of the IEEE 1076 VHDL standard, and partial for the 2008 and 2019 revisions. By using a code generator (LLVM, GCC or, x86_64/i386 only, a built-in one), it is much faster than any interpreted simulator. It can handle very large designs, such as leon3/grlib. GHDL runs on GNU/Linux, Windows and macOS; on x86, x86_64, armv6/armv7/aarch32, aarch64 and ppc64. You can freely download nightly assets, use OCI images (aka Docker/Podman containers), or try building it on your own machine.

    Labcoat: Cleanroom Apps for SuperWikia

    Labcoat; the VHDL graphic emulator.

    Labcoat for SuperWikia Alpha fabrication manages new or revised fabrication processes. Its 'Cleanroom' applets allow codesmiths to access the lab environment, used to create semiconductors, substrate prototypes, chipset instruction blocks and other Labcoat projects. Our extensions in future releases will include UML support for C#/C++ conforming projects, import/export architecture schematics and refactoring sub-projects.
