I am creating a block diagram in Simulink, I would like to access the next data point in a signal. To illustrate this, given that y(n) is my signal, I would like to access y(n+1). I am aware of the "delay" block that would allow me to access y(n-1), however I am unsure how to obtain y(n+1). Thanks for all your help.

Opposite of unit delay is unit prediction and there is no way to predict a signal unless simulation is done up to that point. One way to implement this would be to simulate till the nth step and assume that to be the (n+1)th step and to consider the (n-1)th step as the nth step and so on. This way there is always a signal that acts like a future signal. You might have to reframe your implementation to accommodate this.
If you’re looking for an estimate, you can use estimators such as Kalman filter to predict future behavior.
