AR# 21297 7.1 Spartan-3E Speed Specs - 24-150 MHz DCM warning is incorrect freguency range for Spartan-3E DCM in Low Frequency mode

Keywords: frequency, DCM, dcm, spartan3e, Spartan3E

Urgency: Standard

General Description:
When I run timing analysis on my design that has a PERIOD constraint on the clock at 5 MHz, but I receive a warning that the DCM can work only between 24 MHz to 150 MHz. The data sheet states that it can run at 5MHz, so when is this going to be fixed?

This problem has been fixed in the latest 7.1i Service Pack available at:
http://support.xilinx.com/xlnx/xil_sw_updates_home.jsp
The first service pack containing the fix is 7.1i Service Pack 2.
