1.14. Core Clocking

Core clocking in Stratix® 10 devices makes use of programmable clock tree synthesis.

This technique uses dedicated clock tree routing and switching circuits, and allows the Quartus® Prime software to create the exact clock trees required for your design. Clock tree synthesis minimizes clock tree insertion delay, reduces dynamic power dissipation in the clock tree and allows greater clocking flexibility in the core while still maintaining backwards compatibility with legacy global and regional clocking schemes.

The core clock network in Stratix® 10 devices supports the new Hyperflex® core architecture at clock rates up to 1 GHz. It also supports the hard memory controllers up to 2666 Mbps with a quarter rate transfer to the core. The core clock network is supported by dedicated clock input pins, fractional clock synthesis PLLs, and integer I/O PLLs.
