v3.0.0

Added

• new selections details widget
  • hierarchical view of all items within the current selection
    • a single item can be selected within that view
    • selected item will be highlighted in a different color than the rest of the graph view selection
    • current selection can be moved to a module or grouping by using the respective buttons
  • details section
    • shows additional details for the item selected in the hierarchical view
    • sections can be collapsed and expanded
    • right-click context menu allows to copy strings or Python code to the clipboard and change module name, type, and port names
    • added number of gates, nets, and submodules to module details widget
• new view manager widget
  • now presented in a table view additionally containing information about the time of creation of the view
  • views can be sorted by name and date
• gate library improvements
  • support for gate types with multi-bit pins
  • clear identification of clock pins
• new netlist features
  • module types and named module ports (parsed from netlist or set by user)
  • support for multi-driven nets (i.e., nets with more than one source)
• groupings
  • an interactive container for gates, nets, and modules
  • new groupings widget within the GUI to control groupings
    • allows to be filtered and sorted
    • groupings can be added to the current selection
  • members of a grouping are shown in a dedicated color within the graph view
• new graph view features
  • Python GUI API to control the graph view
  • zoom level of graph view can now be controlled by shortcuts
• netlist utilities
  • added function to deep copy a netlist
  • added function to get the Boolean function of a subgraph
• state-of-the-art suite of benchmark netlists
• new simulator plugin
  • simulates (parts of) a netlist cycle accurate
  • can export to VCD
• added clear_caches to Netlist
• added get_fan_in_endpoint, get_fan_out_endpoint, get_fan_in_endpoints and get_fan_out_endpoints to class Gate

CHANGED

• double-clicking module in module widget will open it in new view
• gate library manager now operates on file paths instead of library names
• liberty gate library parser now supports inout ports, clock statements and bus groups
• netlist parsers
  • VHDL and Verilog parser now use common intermediate structure for parsing
  • attribute parsing for Verilog parser
  • support for inout ports
• all parsers and writers have been moved into plugins
• code refactoring
  • "hal" namespace
  • TitleCase for classes
  • moved to std::filesystem internally
  • split Python API into multiple files
• massively expanded testing coverage
• the project is now affiliated with the Max Planck Institute for Security and Privacy
• reworked core ownership model
  • no more shared_ptr
  • clear ownership management via unique_ptr at necessary locations
  • instances passed via non-owning raw pointers
• updated/fixed the graph algorithms plugin by switching entirely to igraph
• Endpoints are now managed classes as well, owned by the respective nets and passed via pointers
• cleaned up the documentation in many parts of the core
• inverting a Boolean function is now done using ~ instead of !

FIXED

• cone-view now works correctly for modules
• module widget selection is now more consistent with graph view
• inconsistencies with case insensitivity of the VHDL parser fixed
• delete option no longer shown for top module in right-click context menu
• some minor memory leaks in plugin management

REMOVED

• list of nets and gates no longer present in module details widget

DEPRECATED

• accessing the single source of a net is superseeded by accessing its source list to support multi-driven nets
• using !to invert a Boolean function
