CPLD CoolRunner-II - " WARNING:NgdBuild:487 - Parameter 'DIVIDE_BY' on 'CLOCK_DIV16' has an incorrect value data type."


When using the clock divider in a CoolRunner-II NGDBuild, I receive the following warning:

"WARNING:NgdBuild:487 - Parameter 'DIVIDE_BY' on 'CLOCK_DIV16' has an incorrect value data type."

What is the meaning of this warning?


The clock divider in the CoolRunner devices can be used to divide by 2, 4, 6, 8, 10, 12, 14, and 16.

If the clock divider is used to divide by an allowed value, this warning can be safely ignored as the generated logic is correct.

This issue is due to be fixed in a later version of ISE.
