Detailed Description

tnode data structure for a node in a timing graph

  • out_edges: [0..num_edges - 1]. Array of the edges leaving this tnode.
  • num_edges: Number of edges leaving this node.
  • T_arr: Arrival time of the last input signal to this node.
  • T_req: Required arrival time of the last input signal to this node if the critical path is not to be lengthened.
  • type: What is this tnode? (Pad pin, clb pin, subblock pin, etc.)
  • pb_graph_pin: pb pin that this block is connected to
  • block: Which block this pin is connected to
  • index: index of array this tnode belongs to
  • num_critical_input_paths, num_critical_output_paths: Count total number of near critical paths that go through this node *
