The Global Clock Source Details table shows how each clock generator output
connects to global clocks and provides timing clock information. The following figure
illustrates how the outputs of an MMCM instance (src0 and src1) connect to clock
buffers. In the example, the CLKOUT2 output of src1 drives two global clocks: g7 and g8.
Figure 1. Global Clock Source Details Table
The table includes the following columns:
| Column | Description |
|---|---|
| Source Id | Identifier of the clock-generating primitive |
| Global Id | Identifiers of the global clocks driven by the source pin |
| Driver Type/Pin | Output primitive pin that generates the clock |
| Constraint | Highest-priority user-defined constraint applied to the clock buffer, using
the following order:
|
| Site | Clock source location set by you or by the Vivado implementation tools |
| Clock Region | Clock region of the device where the source is located |
| Clock Loads | Number of clock pin loads connected to the source pin |
| Non-Clock Loads | Number of non-clock pin loads connected to the source pin, such as CE pins on FDCE elements |
| Source Clock Period | Period in nanoseconds of the timing clock generated by the source pin. If multiple clocks propagate, the report shows the smallest period |
| Clock | Name of the timing clock generated by the source pin. If multiple clocks
propagate, the report displays Multiple
|
| Driver Pin | Logical name of the clock source pin |
| Net | Logical name of the clock net segment connected to the source pin |
