AXI4-Stream Library

The essential AXI4-Stream toolkit — FIFOs (sync and async), width adapters, mux/demux/arbiter, switch, crosspoint, rate limiter, COBS codecs and more — at genuinely full coverage: 31 of 31 modules, 345 tests.

Getting there found real bugs upstream ships to everyone: single-beat frames silently dropped by the LocalLink bridge, single-beat frames uncounted and non-contiguous tkeep counted as zero bytes in the statistics counter, and a frame joiner that could not even elaborate in its degenerate configuration. Each fix is documented at the point of change in the RTL, with the reasoning.
