2.6.1.1. Empty Partition Clock Source Preservation
Empty partitions preserve clock sources that the Intel® Quartus® Prime software recognizes.
The Intel® Quartus® Prime software recognizes and preserves the following as clock sources for a partition:
- Signals from a PLL.
- Feeds from internal clock inputs on flip-flops, memories, HSSIO, I/O registers, or PLLs outside the partition that you empty.
The Intel® Quartus® Prime software does not recognize the following as clock sources for a partition:
- Nets with sources external to the FPGA that do not feed a clock input inside the FPGA.
- Nets that connect only to combinatorial logic.
- Nets that connect only to an output pin.
- Nets that feed only logic within an empty partition.
