  • Patent number: 6434731
    Abstract: An automated method for designing a signal distribution network in an integrated circuit confines the circuits relating to a particular signal, such as a clock signal, to multiple areas equally distributed over the integrated circuit. Each of the multiple areas have tightly-coupled logic connected to a root driver circuit in which the root driver circuit is connected to the signal input. Within the areas of tightly-coupled logic, user-defined placement circuits or groups such as a programmable clock delay having gates, delays, and splitters are connected to the root driver circuit in accordance with wire capacitance targets and input pin load balancing among all the multiple areas. The input pin load balancing and the wire capacitance targets of the user-defined placement groups connected to the root driver circuit in one of the multiple areas matches the input pin load balancing and the wire capacitance targets of other groups connected to other root driver circuits in other multiple areas.
