Structure cluster and method in programmable logic circuit
Abstract:
A method for clustering logic units in a field programmable integrated chip to generate a set of clusters is disclosed. The clustering step for forming a super cluster comprises a first logic element and a second logic unit a first logic unit and a super cluster, or a first super cluster and a second super cluster. The method includes generating all possible configurations by enumerating all possible two-way relationships combining a driver-and-receiver relationship from a pool of a finite number of dedicated connections. The set of all possible configurations is reduced to a subset of configurations based on one or more multi-dimension criteria. Each dimension in the multi-dimensional criteria is represented by a parameter. The method involves prioritizing a collection of parameters so that a set of selected parameters or a set of selected criteria is used to generate a desirable number of subsets of configurations.
