Abstract:
A method of determining signal delay of a first resource of a plurality of resources of a reconfigurable system, comprising the steps of:(A) configuring a number of resources of the plurality of resources into a first oscillator, wherein the number of resources include the first resource;(B) measuring the oscillating frequency (f.sub.1) of the first oscillator without physically and individually measuring the signal delay of each of the resources that form the first oscillator;(C) reconfiguring the number of resources except the first resource into a second oscillator;(D) measuring the oscillating frequency (f.sub.2) of the second oscillator without physically and individually measuring the signal delay of each of the resources that form the second oscillator;(F) obtaining the signal delay of the first resource from the difference of 1/f.sub.1 and 1/f.sub.2 such that the signal delay of the first resource is accurately determined without physically and individually measuring the signal delay of the first resource.
