Altera Quartus II Settings File - Manual (Page 461)

CLOCK_REGION
Specifies that a signal routed using global routing paths should use the specified clock region. Valid values
are in the form \"Regional Clock Region 1\" or \"Periphery Clock Region 1\" and match the clock region
names displayed in the Chip Planner. This assignment can also be used in conjunction with the \"Global
Signal\" assignment to constrain the logic fed by a clock signal to an area of the chip that is smaller than
the clock region specified by the Global Signal assignment. For example, a Global Signal assignment of
\"Global Clock\" and a Clock Region assignment of \"Regional Clock Region 1\" constrains the logic to the
area fed by Regional Clock Region 1.
