When running a design in ISE 9.1i, MAP produces the following error:

"ERROR:PhysDesignRules:1645 - Unsupported programming. The PLL_ADV comp XXX/XXX/PLL_ADV_INST with programming for attribute RESET_ON_LOSS_OF_LOCK is not supported for this architecture. The RESET_ON_LOSS_OF_LOCK attribute must be changed to FALSE"
