When FSM extraction is turned on and there is a KEEP or DONT_TOUCH attribute on the state machine register, Vivado Synthesis ignores the KEEP or DONT_TOUCH attribute.
To work around this issue, turn off FSM extraction to allow the KEEP or DONT_TOUCH to be used.
The issue is fixed in 2013.1 release of Vivado Synthesis.
