Vcd waveform viewer for mac6/14/2023 ![]() Ĭan synthesize arbitrarily complex VHDL designs into a VHDL 1993 netlist, which can be implicitly orĮxplicitly used in open source or vendor synthesis frameworks. Combined with a GUI-based waveform viewer and a good text editor, GHDL is a very powerful tool for writing, testing and simulating your code.Ĭo-simulation with foreign applications is supported through Verilog Procedural Interface (VPI) and/or VHPIDIRECT. You can freely download nightly assets, use OCI images (aka Docker/Podman containers), or try building it on your own machine (see ‘Getting GHDL’ below).Ĭan write waveforms to GHW, VCD or FST files. ![]() GHDL runs on GNU/Linux, Windows and macOS on x86, x86_64, armv6/armv7/aarch32, aarch64 and ppc64. It can handle very large designs, such as leon3/grlib. Partial support of PSL.īy using a code generator (LLVM, GCC or, x86_64/i386 only, a built-in one), it is much faster than any interpreted simulator. Native program execution is the only way for high speed simulation.ghdlįull support for the 1987, 1993, 2002 versions of the IEEE 1076 VHDL standard, and partial for the latest 2008 revision. GHDL is not an interpreter: it allows you to analyse and elaborate sources for generating machine code from your design. This directory contains the sources of GHDL, the open-source analyzer, compiler, simulator and (experimental) synthesizer for VHDL, a Hardware Description Language (HDL).
