I try use DCM in Basys2 board. But when I compile project I have an error:
ERROR:Place:962 - A DCM / BUFGCTRL clock component pair have been found that are not placed at an optimal DCM / BUFGCTRL
site pair. The DCM component <DCM0> is locked to site <DCM_X0Y1> and the corresponding BUFGCTRL component
<BufgceClk80P180/BUFGMUX> is locked to site <BUFGMUX_X2Y1>. This will not allow the usage of the fast path between
the DCM and the Clock buffer. If this sub optimal condition is acceptable for this design, you may use the
CLOCK_DEDICATED_ROUTE constraint in the .ucf file to demote this message to a WARNING and allow your design to
continue. However, the use of this override is highly discouraged as it may lead to very poor timing results. It is
recommended that this error condition be corrected in the design. A list of all the COMP.PINs used in this clock
placement rule is listed below. These examples can be used directly in the .ucf file to override this clock rule.
< PIN "DCM0.CLK2X180" CLOCK_DEDICATED_ROUTE = FALSE; >

Please help me to solve this error.
