7.1i CPLDFit - The timespec on a clock divider output is not automatically adjusted
Description
The timespec on a clock divider output is not automatically adjusted.
Solution
The Clock Divider in the CoolRunner-II device can divide by 2, 4, 6, 8, 10, 12, 14 or 16. The tools do not automatically adjust the period constraint to account for this. Therefore, if you are using the Clock Divider, you need to constraint for the output frequency of the Clock Divider.
