Changelog

Tracking changes per date:

230719

  • ProbeEdit, a component for interactive debugging (and maybe some end usage as well). It allows you to enter a value (dec/hex) for a signal. It acts as a register so its content will be used in the next clock cycle (one could also think of changing this to act directly by triggering some re-evaluation, not sure). ProbeEdit also implements a proper history buffer so you can reverse the simulation.

  • un_clock method in the Component trait. It does not alter the simulation state (for that we already have a history buffer), components with internal state (e.g., the ProbeEdit component) implements un_clock and keep a local history. Maybe we will have some helper functions to that end.

230718

  • Panes, right click component to display component interior on left panel. Close left panel view by the X (Close) button.

  • Left panel views can be folded/unfolded

230717

  • mips/reg_file update, showcasing interior mutability and gui_vizia poc.

230714

  • fern based logger.

  • Fixed clippy lint for Rust 1.71

  • WIP support for named outputs.

  • Added caching to the Github workflow to improve job times.

230713

  • Added bounds checking for Simulator (set_id_index, get_input_val), panics on out of bounds.
  • Added re-definition check for Simulator, panics on re-definition.
  • Added units tests to the above.

230705

  • Refactoring of Component trait such that logic part is separated from GUI part.

  • Test framework added, where integration (simulation tests are found in the tests folders.)

230703

  • Webhooks for Discord channel.

  • .gitignore to exclude .gv and .json files.

  • SignExtension component.

Compilation times might be annoying. It seems that under Linux there is a lot more dependencies than under Windows, so building SyncRim is faster on Win10 than under Linux (stock settings). There are a number of things to try out to reduce compilation times (and in particular hot iterations).

  • Disable generation of debug (DWARF) info. debug = false (or debug = 0). If stack backtraces are needed use debug = 1, which is still faster than debug = 2 (debug = true equivalent).
  • Use mold instead of lld.

Together debug = 0 and mold linking may yield significant improvements. (On the 7950x3d, hot re-compiles improved from around 4 seconds to 0.3 seconds (in the range of measuring errors for vscode interactions etc.) With debug = true + mold 0.5 seconds or so, both acceptable, mold makes the biggest difference to incremental builds.

See Cargo.toml and .cargo/config.toml for updated configuration. Notice, you need to install mold through your package manager for this to work.

230702

  • path no longer stored in .json model.
  • path passed as &PathBuf to gui and component_store.
  • path stored as PathBuf in the gui.

Finally, SyncRim can now open models through Open (CTRL-O) in gui (ReOpen (Ctrl-R) still works to read manually changed .json).

Notice, if running a simulator compiled from root you cannot load mips models. Instead start from a mips simulator, that can load mips models, e.g., the reg_file or mips examples (or the main in the mips folder). This is expected and desired behavior, a feature not a bug :)
