The Local Clock Details table appears only when the design includes local clocks. A local clock is a clock net that uses regular fabric routing resources instead of global clock routing. This typically occurs when a clock net is not driven by a clock buffer. The information in this table is similar to what you see in the Global Clock Resources table.
The following figure shows an example where a local clock net, driven by the output of a 7 series MMCM, connects directly to a register clock pin (FDRE/C).
