Collaboration diagram for s_rt_node:

Detailed Description

Structure describing one node in a routing tree (used to get net delays incrementally during routing, as pieces are being added).

u.child_list: Pointer to a linked list of linked_rt_edge. Each one of the linked list entries gives a child of this node.
u.next: Used only when this node is on the free list. Gives the next node on the free list.
parent_node: Pointer to the rt_node that is this node's parent (used to make bottom to top traversals).
re_expand: (really boolean). Should this node be put on the heap as part of the partial routing to act as a source for subsequent connections? TRUE->yes, FALSE-> no.
parent_switch: Index of the switch type driving this node (by its parent).
inode: index (ID) of the rr_node that corresponds to this rt_node.
C_downstream: Total downstream capacitance from this rt_node. That is, the total C of the subtree rooted at the current node, including the C of the current node.
R_upstream: Total upstream resistance from this rt_node to the net source, including any rr_node[].R of this node.
Tdel: Time delay for the signal to get from the net source to this node. Includes the time to go through this node.
