The report presents the clocking topology and placement information organized by categories:
- Clock Primitive Utilization
- Global Clock Resources
- Global Clock Source Details
- Local Clock Resources
- Clock Regions utilization details
- Global Clocks placement details
Due to long netlist object names and to the large number of clock nets and clock primitives in typical designs, a short ID is given to specific clock resources:
- A unique Global Id "
g<n>" for each net driven by a clock buffer
- A unique Source Id “
src<n>” for clock generator, such as an MMCM or an input buffer.
- A unique Local Id “
<n>” for clock nets not routed with global clock resources.
The Global Source and Local IDs simplify searching specific clock nets throughout the report. The original netlist object names are available in the last two columns of each table when applicable.
