Quick Question - How to event on multiple clocks rising edges?

Hmm, The two different speed clocks are essentially the same clock, but fed through a PLL...

The second clock is exactly 4x the speed of the first. I was intending to use when the faster clock and slower clock rise at the same time, to show me where the start of a cycle is. This is because I have a statemachine with 4 stages which I need to complete within one slow clock cycle, so thought if I had a 4x clock then when they clock together it triggers the first stage, then the statemachine can run from the faster clock. Using when both clocks rise together to keep the state machine synchronised to the main clock.

Is there a better technique to do this then, rather than what I have been attempting?
