Description

Keywords: clock, DRC, generate

The following warning occurs after I create a Base System Builder Design:

"WARNING:MDT - The value for the parameter clock_generator_0:C_DCM0_CLKIN_PERIOD
-
C:\Xilinx\10.1\EDK\hw\XilinxProcessorIPLib\pcores\clock_generator_v2_01_a\dat
a\clock_generator_v2_1_0.mpd line 181 is not specified in the MHS. As a
result, the default value (8.000) is used from the MPD. However, the value
should be 10.000000. Please add this parameter in the MHS and set it's value
to : 10.000000 . Please note that this warning will be converted to an ERROR
in EDK 11.1"

Solution

You will see one warning for each DCM not used in the clock_generator module. You can safely ignore these warnings because these DCMs are not being used and you do not have to set this parameter.

If you do not want to see the warning, you can set the C_DCMx_CLKIN_PERIOD parameter.
