My slave driver should react not on clock, it should react on Master drivers signals change, how to write it?

Hi,

I need to write driver which is not sync with clock. I should change my slave signals based on signals that master drives. Master drives MCmd, MData and MAddr. My slave should react on any change on any of those signals. I cannot write @(posedge). How I am supposed to write in my slave driver to wait for any change on some of those signals?

Thanks

In reply to d995:

I do not believe your slave works asynchronous while your master is synchronous.
You should also synchronize on your clock.

In reply to d995:

Waiting any change of the signal, you can use:


@(signal);

You can also use “wait” statement to wait for any particular value of the signal.


wait(signal === some-value);

But again, as @ch_sue mentioned, you should review to make sure you are using a correct approach.
