Document Table of Contents Registers with High Immediate Fan-Out Tension

There are two Sink Type options: Endpoint and Immediate Fanout. The immediate fan-outs are the immediately connected nodes (lookup tables, other registers, RAM or DSP blocks, and others) of the register. This fan-out is equivalent to fan-outs that the Chip Planner displays, and in various high fan-out reports. Register duplication directly distributes the immediate fan-outs of a register among the duplicates.
