PowerPlay estimation and asynchronous faster-than-clock signal: no clock domain found

Hi all, I am a newbie and I have a simple task at hand. I am working on a simple controller project on a Max3000A series device with an input signal that is faster than the system clock....

I think you can view the async signal as a clock for the purpose of power.

Thank you for your response kaz. Please, how am I to achieve that? Like below? 

async_signal_like_clock : PROCESS
    BEGIN
        async_signal <= '0';
        wait for 3 * (async_signal_period/5);
        async_signal <= '1';
        wait for 2 * (async_signal_period/5);
    END PROCESS;

Use a suitable clock value that equals average of change rate of your signal.

I don't really understand this statement. Please can you elaborate more on it?

About clock domain, please help explain to me what it means. Thanks once again.

Akanimo.
