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 `Architecture Definitions`_ project
|
|
to prepare bitstream for the chosen 7-Series FPGA chip.
|
|
|
|
The database is generated by the fuzzers and is located in the ``database``
|
|
directory. Each supported chip architecture has its own set of files, they
|
|
are located in ``database/<device_arch>/``. Although the database
|
|
is huge it consists only of a few file types. Some of them are common
|
|
for 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/*``
|
|
|
|
Some files are specific to a given part and are located in a separate directory.
|
|
The directory is named from 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``
