Changelog

All notable changes to this project will be documented in this file.

[0.13.0] -- 2023-03-2023

Added

  • Circuit zooming buttons

Fixed

  • Fixed undefined reference in memory

[0.12.1] -- 2022-03-17

Fixed

  • The cells, tools, engines and transforms namespaces are now exported for non-browser environments.

[0.12.0] -- 2022-02-22

Fixed

  • Fix the lifetime of the event listeners for the sub-windows (Contributor: Yichao Yu)
  • Fix binary mux transform for Yosys 0.12 and later
  • Elkjs layout change marked as batch (Contributor: Yichao Yu)
  • Save IO port orders for subcircuits (Contributor: Yichao Yu)

[0.11.0] -- 2022-02-03

Added

  • The Dff block can now have asynchronous loading.

Changed

  • The elkjs layout engine now includes laying out edges via adding bend points. The SPOrE algorithm was disabled because it did not work well with the change. (Contributor: Yichao Yu)
  • The interface now works better with touch devices. (Contributor: Yichao Yu)

Fixed

  • The *Const family of arithmetic operations is now correctly JSON serialized, and they are better tested. (Contributor: Yichao Yu)
  • Parameter changes (e.g. clock speed) are now propagated to the worker thread in the WebWorker engine.

[0.10.0] -- 2021-10-06

Added

  • The Dff block can now have built-in synchronous reset.
  • The Dff block can now have set and clr inputs for setting/resetting individual bits.
  • The Memory block can now have an initialization value, synchronous and asynchronous reset for synchronous read ports.
  • The Memory block can now have port transparency behavior different for each write port.

Changed

  • The Memory block has working bit enables for write ports.
  • The Memory block can now have single bit write enables.

[0.9.0] -- 2021-08-17

Added

  • A new simulation engine, using Web Workers, has been added. It is more responsible and can be much faster than the original one (25x measured improvement).

Changed

  • Architecture was changed to enable simulation engines running concurrently with the UI.
  • Webpack updated to version 5.

[0.8.0] -- 2021-07-21

Added

  • Circuit graph transformations, which make common circuits generated by Yosys more readable.
  • MuxSparse, a new multiplexer cell for situations when only a few of possible options is defined.
  • ElkJS layout engine, which is (in contrast to Dagre) aware of ports.

Changed

  • Gates can now have more than two inputs.
