# Sample BSDL files

This directory is intentionally **not** populated with a BSDL database.

BSDL files are mandated to be freely available by IEEE 1149.1, but their
redistribution terms vary per vendor, so they are not vendored here. Point the
tests and tools at a local directory instead.

Sources:

- Vendor sites (authoritative): TI, AMD/Xilinx, Intel/Altera, Lattice, NXP, ST…
- [bsdl.info](https://bsdl.info/) — community aggregate (~14k files).
- Quartus / Vivado installs bundle BSDL for their FPGAs.
- For quick local testing, the sibling `bs_explorer` repo ships a few under
  `bs_explorer/data/bsdl_files/` (xcku15p, xcku040, m2gl010t).

> Note: a *configured* FPGA's BSDL differs from the blank device — use the
> blank-device BSDL for connectivity checks.
