v4.1.0

• selection details
  • module icons reflect module color
  • gate icons shape according to gate type
  • user setting to adjust size of or omit icon in upper right corner
• project import/export
  • added export feature: generate zipped project including external gate libraries and python source files
  • added import feature by extracting zipped project
  • added quazip library sources (deps) since recent distributions no longer link binary packages against qt5
• netlist parsers
  • added (limited) support for 'defparam' statements to Verilog parser
  • added support for pin assignments by order instead of name to Verilog and VHDL parser
• GUI comments
  • user can add comments to gates and modules to take notes on the reverse engineering progress
  • comments are shown in the graph view (as little notes on the gate/module boxes) and in the selection details widget
• plugin netlist_preprocessing
  • collection of utility functions preparing a raw netlist for further analysis
  • remove LUT fan-in endpoints that do not show up in the LUT's boolean function via remove_unused_lut_inputs
  • remove buffer gates via remove_buffers, also dynamically by analyzing Boolean function and connected inputs
  • remove redundant gates via remove_redundant_logic, i.e., gates of equal type with identical inputs
  • remove unconnected gates/nets via remove_unconnected_gates and remove_unconnected_nets
  • simplify LUT configuration strings based on constant inputs via simplify_lut_inits
• plugin bitorder_propagation
  • propagate a known order of input/output pins within module pin groups to other connected modules
• decorators
  • BooleanFunctionDecorator
    • substitute power and ground nets/pins by constant values in Boolean functions via substitute_power_ground_nets and substitute_power_ground_pins
    • get a concatenated Boolean function corresponding to a vector of nets or Boolean functions via get_boolean_function_from`
  • BooleanFunctionNetDecorator
    • get a unique Boolean function variable for a net via get_boolean_variable and get_boolean_variable_name
    • get the net corresponding to a unique Boolean function variable via get_net_from
    • get the net ID corresponding to a unique Boolean function variable via get_net_id_from
  • SubgraphNetlistDecorator
    • copy a subgraph of the netlist via copy_subgraph_netlist
    • get the Boolean function of a subgraph via get_subgraph_function
    • get the inputs to the Boolean function of a subgraph without computing the Boolean function via get_subgraph_function_inputs
• miscellaneous
  • added functions get_pin_names, get_input_pins, get_input_pin_names, get_output_pins, and get_output_pin_names to class Module
  • added function BooleanFunction::get_truth_table_as_string that returns the truth table of a Boolean function as a formatted string
  • added missing GND, VCC, and RAM gate types to the ICE40ULTRA gate library
  • added Python bindings for the HAL project manager
  • added new GUI dialog for creating an empty project (without providing a netlist)
  • changed all example netlists to be HAL projects
  • API cleanup for plugin solve_fsm
• bugfixes
  • fixed Verilog and VHDL parser ignoring pin order of modules
  • fixed order of module pins in Verilog writer
  • fixed some errors in the Python documentation
  • fixed pin types of power and ground gate types in various gate libraries
  • fixed spamming the log with messages related to module pins
  • fixed segfault that sometimes occurred when deleting a module
  • fixed saving absolute paths for Python files and not copying them to the new project folder when using Save as...
  • fixed some project manager bugs related to inaccessible files
  • fixed missing Python binding for GateType::get_pin_groups
  • fixed incorrect undo action for "fold parent module"
  • fixed some internal data structure of the Verilog and VHDL parsers not being cleared after each instantiation attempt
  • fixed wrong gate type properties for MUX gates in various gate libraries
  • fixed net and instance aliasing in VHDL and Verilog parser
  • fixed netlist parser bug related to unconnected module pins that are being directly assigned to another wire/signal in the module/entity body
  • fixed get_pins returning pins in wrong order if no filter is specified
