CHANGELOG.md

Changelog

1.4.2

Added

  • Publish package discovery metadata, the README, the changelog, and the MIT license with this version.

Compatibility

  • No component API or dependency changes from 1.4.1.

1.4.0

Changed

  • Breaking API rename: the asynchronous FIFO is now named AsyncFifo<T, CAPACITY, STORAGE>. Update declarations and constructor calls when upgrading from 1.3.0; no compatibility alias is provided.
  • Storage-provider names are now AsyncFifoArray, AsyncFifoBlockRam and AsyncFifoDistributedRam. The default remains AsyncFifoArray<T, CAPACITY>.
  • Renamed internal clock-domain components and native test helpers consistently; the FIFO test component is now AsyncFifoTest.
  • Updated README examples, storage guidance and FIFO documentation. The usage guide is now docs/async-fifo.md.

Constructor parameters, generic storage selection, clock-domain behavior, transfer timing and coordinated-clear semantics are unchanged. Existing single-clock collection APIs are unchanged.

1.3.0

Added

  • An asynchronous FIFO for independent write/read clocks, with conservative full/empty signals, edge-level acceptance, registered read responses and coordinated-clear acknowledgments.
  • Default array storage and optional block-memory and distributed-memory specializations for the asynchronous FIFO.
  • Compile-time storage selection through IFifoStorage<T, GEOMETRY>, FifoStorageGeometry<CAPACITY> and a parameterless-construction constraint.
  • Native Livt tests under tests/fifo covering two clock contexts, FIFO fill/drain, coordinated clear and reuse.
  • FIFO usage, storage-selection, timing and clock-domain-crossing guidance.

Changed

  • Separated FIFO payload ownership from pointer/clear control without adding another public FIFO API or a runtime storage selector.
  • Applied the Livt Design Guide to the new FIFO sources, with one component per file, documented responsibilities and explicit test initialization.

Fixed

  • Qualified five pre-existing Stack/List/Queue test constructors to resolve ambiguous names with the installed compiler; production behavior is unchanged.

Known limitations

  • Memory styles are hints. MAX 10 M9K mapping, resource counts, timing and physical CDC sign-off require a selected device and vendor-tool reports.
  • Storage providers must have a combinational read tap. Scheduled or registered read RAMs from Livt.IO cannot be passed directly to this interface.
  • Existing single-clock Fifo/Queue/Stack/List/CircularBuffer storage APIs are unchanged.
