template<typename graph_t>
Netlist struct

Represents a netlist, which is implemented using a graph-like data structure.

The Netlist struct contains various properties and data structures to represent the netlist, including:

  • gr: The underlying graph-like data structure used to represent the netlist.
  • modules: A view of the module nodes in the graph.
  • nets: A view of the net nodes in the graph.
  • num_modules: The number of module nodes in the netlist.
  • num_nets: The number of net nodes in the netlist.
  • num_pads: The number of pad nodes in the netlist.
  • max_degree: The maximum degree of any node in the netlist.
  • max_net_degree: The maximum degree of any net node in the netlist.
  • module_weight: A vector of weights for each module node.
  • has_fixed_modules: A flag indicating whether the netlist has any fixed module nodes.
  • module_fixed: A set of fixed module nodes.

Function documentation

template<typename graph_t _1>
Netlist<_1>::Netlist(graph_t gr, const nodeview_t& modules, const nodeview_t& nets)

Constructs a new Netlist object.

Parameters
gr in The graph representing the netlist.
modules in The module nodes in the netlist.
nets in The net nodes in the netlist.

Constructs a Netlist object from the given graph, module nodes, and net nodes.

This constructor initializes a Netlist object with the provided graph, module nodes, and net nodes.

The constructor initializes the Netlist object with the provided graph, modules, and nets. It also calculates the maximum degree of the modules and nets, and sets flags indicating whether the modules have fixed positions.
