Surfer 0.4.0

Surfer is a waveform viewer designed to be extensible and to run anywhere, both as a native app and on the web.

Added

• New commands goto_cursor, cursor_set, marker_set, marker_remove. Markers can be accessed through their names or numbers as #3 etc.
• It is possible to pan with the right/secondary mouse button.
• Change the relative size of the Scope and Variable lists.
• Fixed-point translators based on index value (fractional bits have negative indices), suitable for sfixed VHDL-types etc.
• Add grouping of variables (and groups).
• It is possible to add scopes as groups, possibly recursively.
• Surfer automatically select a corresponding translator for the VHDL types signed, unsigned, sfixed, and ufixed.
• It is now possible to drop state files onto Surfer to load them.
• A script, surfer.sh, that can be used to easily start Windows Surfer from WSL. Download from repo and follow the instructions in the script.
• It is now possible to copy the variable name of the focused variable by right-clicking on the name.
• Right-click menu for scopes to add variables in scopes.
• Ctrl+s now saves the state file.
• If there is a file ending with .surf.ron in the current directory, there will be a dialog asking if it should be loaded (configurable to either ask, always load, or never load).
• The variable filter can now filter based on port direction and optionally group based on port direction.
• Measure time by holding shift and left-click (primary mouse button). Configure color and line width using measure in theme. Can be changed to not need shift by setting the config primary_button_drag_behavior to Measure (dragging the cursor will now require shift) or by menu entry.
• The arrow between transactions can now be fully configured, including line width and arrow properties.
• The maximum size of the "X" between vector transitions can be configured using `vector_transition_width´ (default 6).
• It is possible to configure the mouse gestures.
• LoongArch64 (LA64) instruction translator.
• The height of the waves can be modified by right-clicking on the variable name and use the "Height" submenu. The available options can be configured using waveforms_line_height_multiples.
• There is now an app_id for use with Wayland to identify the Surfer window: org.surfer-project.surfer.
• It is now possible to run a command file/script using the menu, toolbar, or the new commands: run_command_file or run_command_file_from_url.
• New config of wide signal fill: wide_opacity
• Translators can now be written in WASM and loaded at runtime.
• Translators an now translate variable names into source code locations
• Right click now pans the view
• "Expand scope" in variable context menu selects the containing scope and expand the tree.
• Two accessible color themes, one light and one dark, based on Petroff.
• You can now scale the UI with ctrl/+ and ctrl/-
• Various changes to the Waveform Control Protocol
  • Add add_scope_recursive
  • Add add_scope
  • Fix greetings
  • Send waveforms_loaded on loads not triggered by WCP
  • Add sources to waveforms_loaded
  • Require greetings
  • Change the WCP injection API to be more similar to CXXRTL
  • Adds events for drivers and loads to a signal

Changed

• surver now sends data in a compressed format.
• The scope list is sorted.
• m now adds a marker (next number), while toggling the menu is changed to Alt+m.
• Surfer state-files now ends with .surf.ron.
• To drag the cursor, you now need to hold shift.
• BREAKING: Mouse gesture line style moved from config to theme.
• BREAKING: Arrow between transactions can be fully configured, so relation_arrow is now a subsection and not a simple color.
• BREAKING: The config settings autoreload_files and auto_load_sibling_state_files have changed format from Option<bool> to an enum with the values Always, Never, and Ask.

Fixed

• Crash when adding too many viewports/trying to draw zero-sized viewports.
• It is again possible to correctly build Surfer with or without selected features.
• Wellen backend updated with better support for GHW-files and incomplete FST-files among other things.
• Loading files with many variables should now be significantly faster.
• It is no longer possible to zoom in arbitrarily much, avoiding some issues related to that.
• Crash when using automatic time scale and underlying waveform file has very high resolution.
• The mouse gesture zoom in now starts at the exact click location in x-direction.
• Surfer should be more responsible when having an active scope with a large number of variables.
• Time scale is no longer reset after reload.
• Adding many variables (recursive scopes etc) in one go, should be significantly faster.
• Add background to multi-bit signals. (Enabled in themes, default in the light theme)
• The right-most clock edge line is now drawn.
• More settings are saved in the state.
• Crash when zooming before waveform file is fully loaded.

Removed

Other

• egui is updated to 0.33. This can lead to minor visual changes, including more clear text rendering. If something looks worse, please report!
