Detailed Description

Lists all the important information about a certain segment type. Only used if the route_type is DETAILED. [0 .. det_routing_arch.num_segment]

• frequency: ratio of tracks which are of this segment type.
• length: Length (in clbs) of the segment.
• wire_switch: Index of the switch type that connects other wires *to* this segment.
• opin_switch: Index of the switch type that connects output pins (OPINs) *to* this segment.
• frac_cb: The fraction of logic blocks along its length to which this segment can connect. (i.e. internal population).
• frac_sb: The fraction of the length + 1 switch blocks along the segment to which the segment can connect. Segments that aren't long lines must connect to at least two switch boxes.
• Cmetal: Capacitance of a routing track, per unit logic block length.
• Rmetal: Resistance of a routing track, per unit logic block length.
• drivers: How do signals driving a routing track connect to the track? (UDSD by AY)
