9.1i Floorplan Editor - Cannot place BUFGMUX component


When I try to place my BUFGMUX component, Floorplan Editor does not allow me to place the BUFGMUX in an appropriate location, and then I receive the following error:

"ERROR:Place:592 - A clock IOB / BUFGCTRL clock component pair have been found that are not placed at an optimal clock IOB / BUFGCTRL site pair. The clock IOB component <PAD_CDD_ADC_CLKDATA> is placed at site <AE18>. And the corresponding BUFG component <mux21_cddclk/I_cdd_adc_clkdata_RNI2FU1/BUFGCTRL> is placed at site


When is this going to be fixed?


This problem has been fixed in the latest 9.1i Service Pack available at:

The first service pack containing the fix is 9.1i Service Pack 2.
