Abstract:
1. A method of determining an implementation of a design on an integrated circuit device, the method comprising: determining statistics of attributes of elements of the device, wherein the statistics comprise a probability distribution function (PDF) of a timing delay for each interconnect in a signal path of the design; determining configuration information specifying at least a portion of a configuration of the design on the device, wherein the configuration of the design associates portions of the design with at least a portion of the elements of the device; evaluating a suitability of the configuration according to at least one design criteria using the statistics of the attributes of the associated elements of the device, wherein the statistics comprise a statistical criticality value that provides a probability that an interconnect is included in a critical path, and wherein the probability that an interconnect is included in a critical path is derived from the PDF of the timing delay for that interconnect, wherein evaluating the suitability of the configuration comprises determining a cost function value for the configuration based on the configuration information and the statistics of the attributes of the associated elements of the device and wherein the cost function includes the statistical criticality value for each interconnect of the signal path; and selecting the configuration information in response to the configuration satisfying the at least one design criteria.
