Method of wiring power service terminals to a power network in a semiconductor integrated circuit

Disclosed is a method of routing power from a power network to one or more power service terminals within a voltage island, comprising: dividing the power network into segments; creating power service terminal to segment connections based on a first set of criteria; removing selected power service terminal to segment connections based on a second set of criteria; and selecting one power service terminal to segment connection for each the power service terminal. The first criteria is includes power drop, wire length, wire size, wiring layer restrictions and the second criteria includes electro-migration, wire length and current criteria.
