Global Clocks
There are eight global clock networks in the Eclipse device family. Global clocks can drive logic cell, I/O, and
RAM blocks in the device. Five global clocks have access to a Quad Net (local clock network) connection with
a programmable connection to the register inputs. Global clock pins are 2.5 V, LVCMOS2, compliant.
