SOPC Builder Does Not Recognize Decimal Points

If you assign the PLL clock with a value with decimals, SOPC Builder takes only the whole number and does not recognize the value after the decimal point. When you generate the system, the The PLL reference clock of <value> does not match the clock frequency input to refclk error message appears.

This issue affects all designs that have a PLL clock value with decimals.

Your system cannot be generated.

Ignore the error message, and generate the system by holding down the Ctrl key on the keyboard while clicking Generate in SOPC Builder.

This issue will be fixed in a future version of the DDR and DDR2 SDRAM Controllers with ALTMEMPHY IP.
