Directory structure

• src: sources of GHDL, all of them in Ada.
• libraries: mostly third party libraries such as, ieee, std, synopsys and vital. Except for a few shell and Python scripts, all the content is written in VHDL.
  • Vendors like Altera, Lattice and Xilinx have their own simulation libraries, especially for FPGA primitives, soft and hard macros. These libraries cannot be shipped with GHDL, but we offer prepared compile scripts to pre-compile the vendor libraries, if the vendor tool is present on the computer. These are located in libraries/vendor. See Precompile Vendor Primitives for information on how to use them.
• dist: scripts and auxiliary files to build GHDL in different environments:
  • gcc: header and configuration files to build GHDL with GCC (all platforms).
  • linux: build and test script written in shell, and other auxiliary files used to i) launch docker containers and ii) automate multiple builds in Travis CI.
  • windows:
    • mcode:
    • appveyor:
• doc: Markdown and reStructuredText sources and auxiliary files to build the documentation with Sphinx. In fact, Read the Docs (RTD) is used to automatically build and deploy this site and/or PDF you are reading.
• testsuite: files used for testing.
• .yml configuration files for CI environments (readthedocs, travis, and appveyor) and ignore files for source control management tools (git and .hg).
• Files for building GHDL: configure and Makefile.in.
• Auxiliary files for development: .gdbinit and ghdl.gpr.in (GNAT project file).
• Text files: COPYING.md, NEWS.md, and README.md.
