 +<​code>​
 +The Virtex-6 FPGA MMCM has the following new requirements:​
 +  1. A calibration circuit is required to be inserted into the user design for all MMCM designs.
 +  2. The minimum VCO frequency of the MMCM is now 600 MHz.
 +  3. The CLKFBOUT_MULT_F attribute (the multiply of the MMCM) cannot be set to fractional values, or a value of 1, 2, 3, or 4. 
 +...
 +11.5 ISE and later software tools automatically insert the circuit into designs using MMCMs during the MAP phase of software implementation.
