Abstract
A method of grouping clock domains includes: separating a plurality of test clocks into a plurality of domain groups by adding to each respective one of the plurality of domain groups those test clocks that originate from a same clock source and have a unique clock divider ratio; sorting the domain groups in decreasing order of size; and creating a plurality of parts by adding the respective one of the plurality of domain groups to a first one of the plurality of parts in which already present test clocks have a different clock source, and creating a new part and adding the respective one of the plurality of domain groups to the new part when test clocks present in the respective one of the plurality of domain groups originate from a respective same clock source and have a different clock divider ratio as test clocks present in all previously-created parts.
