It has: - -* a driver (sources in :ghdlsrc:`src/ghdldrv <ghdldrv>`) to call the programs (compiler, assembler, linker) if needed. - -* a runtime library named GRT (sources in :ghdlsrc:`src/grt <grt>`) to help execution at run-time. This ensures that execution is cycle-accurate. - -* a front-end (sources in :ghdlsrc:`src/vhdl <vhdl>`) to parse and analyse VHDL. See :ref:`INT:Frontend` and :ref:`INT:AST`. - -* multiple back-ends to generate either code or netlists. - - * Three for :ref:`simulation <USING:Simulation>` (sources are in :ghdlsrc:`src/ortho <ortho>`): mcode, LLVM and GCC. See :ref:`BUILD`. - * Two for :ref:`synthesis <USING:Synthesis>` (sources in :ghdlsrc:`src/synth <synth>`): :ref:`--synth <Synth:command>` and :ref:`Synth:plugin`. - -The architecture is modular. For example, the front-end in the ``libghdl`` library is used for the language server. - -The main work is performed by the front-end, which is documented in the next chapter. |
