3.4.4. Global Routing

FPGAs have dedicated clock trees that distribute high fan-out signals to various sections of the devices. In the FPGA system that the Intel® Arria® 10 FPGA Development Kit Reference Platform targets, global routing can distribute high fan-out signals regionally or globally. Regional distribution applies across any quadrant of the device. Global distribution applies across the entire device.

There is no restriction on the placement location of the OpenCL™ kernel on the device. As a result, the kernel clocks and kernel reset must distribute high fan-out signals globally.

Note: To support PR, global routing for the Kernel Reset signal that drives logic inside a PR region requires special handling. Refer to the Partial Reconfiguration section for more information.
