Method of flexible clock placement for integrated circuit designs using integer linear programming

摘要

A method of global clock placement for a circuit design to be implemented on a programmable logic device (PLD) can include identifying clock properties for the circuit design and identifying physical clock region attributes for the PLD. The method further can include specifying an Integer Linear Programming formulation (ILP) of a clock placement problem for the circuit design from the clock properties and the physical clock region attributes. The ILP formulation can be solved to determine whether a feasible clock placement exists for the circuit design.
