Abstract
A method, system and computer program product for implementing enhanced clock tree distributions to decouple across N-level hierarchical entities of an integrated circuit chip. Local clock tree distributions are constructed. Top clock tree distributions are constructed. Then constructing and routing a top clock tree is provided. The local clock tree distributions and the top clock tree distributions are independently constructed, each using an equivalent local clock distribution of high performance buffers to balance the clock block regions.
