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.
Features
- Partial support of PSL
- Can write waveforms to GHW, VCD or FST files
- Co-simulation with foreign applications is supported through Verilog Procedural Interface (VPI) and/or VHPIDIRECT
- an synthesize arbitrarily complex VHDL designs into a VHDL 1993 netlist
- Supported third party projects: Yosys
- GHDL is available through the default package manager on most distributions: Debian/Ubuntu, Fedora, Arch Linux, MSYS2, etc.
