Strategy to monitor single signals

In reply to Rsignori92:

Hi Rsignori92, thanks for your response. What if we are not talking specifically about “interrupt” signal ?
let`s say we have some signal_x that change according to (in the DUT):
assign signal_x = (signal_y && signal_z);
while signal_y and signal_z change absolutely randomly.
What would be the preferred method of sampling and transmitting the signal to SB from monitor?

Thanks
