1. A processor-implemented method to execute on one or more processors that perform the method, comprising: associating at least one data token with a clock domain of a multi-clock domain netlist; determining a durational relationship between clock periods associated with the clock domain and at least one other clock domain of the multi-clock domain netlist; and transforming the at least one data token when using the at least one data token in the at least one other clock domain, based on the relationship.
