1.1. Clock Networks Overview

Intel Agilex® 7 FPGA M-Series devices contain dedicated resources for distributing signals throughout the fabric. Typically, you use these resources for clock signals and other signals with low-skew requirements. In M-Series devices, these resources are implemented as a programmable clock routing network, which allows for the implementation of various low-skew clock trees.
