=========== Description =========== The main goal of the X-Ray Project is to provide information about Xilinx 7-Series FPGA internals. All obtained chip data is stored in the project's database and is used by the `Architecture Definitions`_ project to produce a bitstream for the chosen 7-Series FPGA chip. The database files are generated by the :doc:`fuzzers <../db_dev_process/fuzzers/index>` and are located in the ``database`` directory. Each supported chip architecture has its own set of files, which are located in ``database//``. The database can be quite huge, however it consists only of a few file types. Some of them are common for the whole 7-Series architecture, but some of them are part specific. .. _Architecture Definitions: https://github.com/SymbiFlow/symbiflow-arch-defs Files common for whole 7-Series family: - ``mask_*`` - ``ppips_*`` - ``segbits_*`` - ``site_type_*`` - ``tile_type_*`` - ``timings/*`` The files specific to a given part are located in a separate directory which is named after the FPGA part name i.e *xc7a35tcpg236-1* or *xc7a50tfgg484-1*. Files specific for the particular FPGA part: - ``package_pins.csv`` - ``part.json`` - ``part.yaml`` - ``tileconn.json`` - ``tilegrid.json``
