Abstract
Buffers are placed on selected nets coupled to input and output pins of entities in an IC device. This includes loading selected input and output pins of entities prior to respectively buffering nets of the entities and buffering in successive iterations, which includes setting artificial loads on selected input pins. The buffering in a current iteration is limited to i) buffering nets on the current iteration entity for receivers on the current iteration entity and ii) buffering nets on the current iteration entity directly coupled to respective nets of an immediately adjacent entity that has been buffered already in a preceding one of iterations, but only if the already buffered net is coupled to a receiver on its own net or a receiver on some other already buffered net via nets that have all been buffered via one or more of the preceding iterations.
