It has: + +* a driver (sources in :file:`src/ghdldrv`) to call the programs (compiler, assembler, linker) if needed. + +* a library (sources in :file:`src/grt`) to help execution at run-time. + +* a front-end (sources in :file:`src/vhdl`) to parse and analyse VHDL. + +* a back-end (in fact many, sources are in :file:`src/ortho`) to generate code. + +The architecture is modular. For example, it is possible to use the front-end in the `libghdl` library for the language server or to do synthesis (sources in :file:`src/synth`) instead of code generation. + +The main work is performed by the front-end, which is documented in the next chapter. |
